Facts.

On June 13, 1969, after a trial to the court, the defendant, Clifton Wells, was convicted of armed robbery and first-degree murder, and sentenced to thirty years' imprisonment on the armed robbery conviction and a consecutive term of life imprisonment on the murder conviction.

The crimes for which the defendant was convicted occurred on Sunday morning, November 3, 1968, at the residence of the victim, Mr. Frederick Gens, an eighty-one-year-old resident of the city of Milwaukee.

The case of the state was built upon the testimony of the defendant's accomplice, Miss Kristy Ruhe, who waived immunity and testified, and two eyewitnesses, John Eiland and Lee Pharm, plus the hospital records of Mr. Gens, received in evidence by stipulation.

Kristy Ruhe testified that, prior to the date of the crimes, the defendant informed her of his plan to rob an old man who lived at 1429 West Juneau, Milwaukee. She testified that the defendant, on the date of the crimes, told her they were going to 1429 West Juneau to rob the old man; that she was to knock on the door and tell the old man the defendant wanted to speak to him; that the defendant threatened her life if she did not go through with the plan; and that he picked up an empty bottle and the two of them left. She testified the defendant concealed himself on the front porch, and she knocked on the door. When Mr. Gens answered, she told him the defendant would like to speak to him. The old man stepped out on the porch and, according to her testimony, the defendant then struck him on the head with the bottle. She left then, she testified, but before leaving, saw the defendant strike one blow to the head of the old man and raise the bottle as if to strike again.

One eyewitness, John Eiland, who had been working underneath a car in the parking lot next to the Gens' residence, testified that his attention was attracted by noise from the porch and the sound of someone groaning "don't, don't." He testified that he crawled out from under the car in time to see the defendant strike the old man on the head two or three times with the bottle causing the old man to fall on his stomach on the floor of the porch. He testified the bottle appeared to be a "family-sized" coke bottle. He testified he saw the defendant strike the old man two or three more times after the victim lay, face down, on the porch floor. He testified that he shouted at the defendant, "don't kill the old man, don't beat him to death. . . ." He testified the defendant then reached into the victim's pocket and took a wallet from it.

The other eyewitness, Lee Pharm, who was in the building about 100 feet away, testified that his attention was attracted by the noise of a beating which sounded to him like the noise made by children jumping up and down on the top of an automobile. He testified he saw the defendant, whom he knew from having seen and spoken to him around the neighborhood previously, deliver several blows with the bottle to the head of the old man. He testified that he saw the defendant take something from the pocket of the old man before defendant fled from the scene. After the defendant left, Mr. Gens staggered along the wall back into the house, leaving blood all over the porch. As he entered the house, he was met by his landlady. She sat him down on the bed and went for help. Mr. Gens was then taken to the hospital.

The county emergency hospital records received into evidence by stipulation showed the victim was admitted to the hospital shortly after 10 a.m. Where it was discovered that he had been beaten extensively about the head and chest, suffering, among other injuries, four deep scalp lacerations and a fractured skull. His condition worsened, and he died at 7:15 p.m. that evening. An autopsy revealed that death was caused by a skull fracture with hemorrhage and cerebral damage.

The defendant took the stand in his own defense and denied any involvement in the crime. He stated that, after the taverns closed early Sunday morning, November 3, 1968, he went to an "after hours place" staying there until 9 or 10 o'clock Sunday morning. He claimed to have gone from the "after hours place" to the home of one Charles Carpenter. In rebuttal, the state produced the testimony of Frank Watson, one of defendant's claimed companions on the previous Saturday night, who stated that he had not been with the defendant that evening as the defendant had claimed. The state produced Charles Carpenter who testified he had seen the defendant at a gambling party early Sunday morning, but that he and the defendant had parted company at 8 a.m. on Sunday morning, November 3d, and that he had not seen the defendant again that day.

From the judgments of conviction and sentence and the order denying postconviction motions, the defendant appeals.

ROBERT W. HANSEN, J.

The record in this case sets forth the standard operating procedures that mark the mugging-type robbery.

There is the selection of the victim. Senior citizens, particularly those living alone and suffering the infirmities of advancing years, are preferred targets. Here the victim, Frederick Gens, was an eighty-one-year-old man, living alone in a rented room.

There is the selection of the time and place. By advance surveillance or "stakeout," a time and place are selected when it is predictable that the victim will be alone. Here the time of the assault was 9:30 a.m., on a Sunday morning; the place, the porch of the rooming house where the victim lived.

There is the use of an accomplice as decoy and lookout. The role of the accomplice is to engage the attention and disarm the suspicions of the selected victim, as well as to serve as lookout for the police or other unwelcome intruders. Here a woman associate was used to persuade the victim to step out onto his porch, and to keep watch. She fled, however, soon after beating commenced.

There is the selection of the weapon to be used. The function of the weapon in a mugging is to make it unlikely that the victim will have time to shout for help or have any chance to make any resistance. Thus, a gun, if selected, is as likely to be wielded as a club against the skull as it is to be pointed at the victim. Here the weapon chosen was a family-sized soda water bottle.

There is an immediate resort to violence. Typically, the mugger, without warning, jumps on the victim and commences beating him into a state of helplessness. Unlike the professional bank robber, the mugger hits first, asks questions afterwards. Here the defendant leaped at the victim, beat him about the head, knocked him down, beat him some more, and took his wallet (containing $16 in currency).

There is a savagery to the beatings administered. The brutal beatings that characterize most muggings go beyond the purpose of securing silence or preventing resistance. The degree and type of violence used goes far beyond the jostling of the targeted victim by a pick-pocket or purse snatcher. Here the defendant, after he had clubbed the eighty-one-year-old victim to the floor of the porch, jumped on him as he lay prone, and continued or renewed beating him about the head. There is the trip to the hospital for the victim. Unless beaten to death on the scene, the mugging victim usually requires hospital treatment because of the brutal beating he suffered. Here the victim was admitted to the county emergency hospital shortly after 10 a.m. where it was ascertained that he had been beaten extensively about the head and chest, suffering, among other injuries, four deep scalp lacerations and a fractured skull. It is stipulated that he died of the skull fracture and cerebral damage.

Given a record establishing the death of a victim of a mugging-type robbery, postconviction counsel argues that only third-degree murder — murder while engaged in the commission of a felony (sec. 940.03, Stats.) — was established, not first-degree murder — causing the death of another human being with intent to kill that person (sec. 940.01). Counsel argues that the defendant may have intended to beat up Mr. Gens and take his money, but did not intend to take his life. In other words, the defendant may have intended to take his victim to the threshold, but did not intend to push him over it. The contention is that the defendant must be held to have intended only to take his victim up to the doorstep of death, even though he turned out to be a poor judge of distance.

Seldom is an intent to kill ascertainable from the lips of the intender. Never can it be established by a retroactive mind-reading effort to determine what the actor was thinking when he planned and executed the act. That would require a crystal ball that re-created the past rather than sought to peer into the future. So as an objective test to determine the subjective intent of the doer of a deed, the courts rely upon a presumption, well stated by this court to be:

"In the absence of evidence to the contrary, he who takes the life of another by the infliction of a wound naturally and probably calculated to produce death is presumed to have intended that result and to be guilty murder in the first degree under our statutes. . . ." Farino v. State (1931), 203 Wis. 374, 380, 234 N.W. 366. See also: Gelhaar v. State (1969), 41 Wis.2d 230, 163 N.W.2d 609; Greer v. State (1968), 40 Wis.2d 72, 161 N.W.2d 255.

Evidence of contrary intention may rebut the presumption. See: Melli v. State (1936), 220 Wis. 419, 265 N.W. 79; Gelhaar v. State, supra, Greer v. State, supra; Beauregard v. State (1911), 146 Wis. 280, 131 N.W. 347.

It is this test of presumptive intent that the trial court correctly followed in finding the defendant to have intended the death of the victim, the court finding:

". . . there is an intent to kill a human being, manifested by the actions of the defendant, and he is bound by the usual and ordinary and probable results of his free and deliberate acts. If there are no circumstances to rebut the presumption, the law presumes that death was intended, if a person uses such means as would cause death, unless there are circumstances to prevent or rebut the presumption, which, in this case, do not exist."

Postconviction counsel concedes that this court has repeatedly approved the application of the test of presumptive intent in murder and attempted murder cases, but points out these were cases involving guns or knives, noting that, ". . . In all of these cases the weapon used was intrinsically lethal — a gun or knife — and the facts surrounding the use of the weapon indicated death was intended. . . ." The lethal or death-dealing aspect of a particular weapon derives from the manner and circumstances surrounding its use as much as from its physical properties. When a blackjack or large bottle is swung repeatedly against the skull of a defenseless person, death is as predictable a consequence as when there is involved the thrust of a steak knife. It is the circumstances surrounding the use of the weapon which must be considered in each case.

As to the facts and circumstances in this case, defendant's brief states, in part: "Taking the evidence most favorably to the State," as it is to be taken on a challenge to a conviction, "it indicates that the defendant struck Mr. Gens two or three times with an empty 10-ounce soda water bottle; that the blows were not administered with sufficient force to knock Mr. Gens unconscious. . . ." That understates the case. While the record does not disclose the precise number of blows struck, the hospital findings establish that at least four of the blows were of sufficient force to lacerate the defendant's scalp deeply. It is stipulated that the cause of death was a fractured skull, so one of the blows was of sufficient strength to be skull-fracturing. One eyewitness described the noise of the blows like that of children jumping up and down on the hood of an automobile. Another eyewitness heard a sound like breaking bottles or hitting on walls, and heard someone groan, "don't, don't." Coming up from his position under his auto, he saw defendant strike the old man, who was then standing, a couple of times on his head, knocking him down, and then strike him two or three more times after he lay prone. The ferocity of the blows was such as to prompt the witness to tell the defendant not to beat the old man to death. Such testimony is not only indicative of the severity, as well as repetition of blows, but gives a two-phase aspect to the sequence of events. The first sequence of blows was struck while the victim was standing. The second series of blows, whether viewed as a continuance or renewal of attack, was delivered when the victim had been knocked down and lay helpless on his stomach on the floor. As to the second, it cannot be contended that the blows were intended or required to remove the possibility of spirited resistance by the eighty-one-year-old victim, by then knocked prone, rendered helpless and pleading only, "don't, don't." The defendant did not stop beating the old man until he became aware that he was being observed by a bystander who was approaching, hammer in hand.

Defendant's counsel on appeal argues that the presumptive intent never arose in this case, or, if it did, it was rebutted by the circumstances surrounding the crime. We agree with the trial court finding that presumptive intent to kill was established, and not rebutted. However, while not quoted nor challenged by defense counsel, the trial court interpolated in making his findings: ". . . So, if he wants to take a chance and use a Fanta soda water bottle on the skull of that defenseless old man and that man dies therefrom, that is murder in the 1st degree, under all the evidence. . . ." (Emphasis supplied.) Without the last four words, the statement might suggest that a single swipe with an empty bottle at the head of an older person creates a presumption of intent to kill, which would be neither good law nor good common sense. With the qualification, "under all the evidence," the reference is to "all the evidence" in this record in this case against this defendant. That evidence supports a finding that the defendant repeatedly bludgeoned an aged man about the head — continuing or renewing the bludgeoning after the victim had been knocked down — inflicting, among other injuries, four deep scalp lacerations and a skull fracture, the stipulated cause of death. That evidence clearly sustains the finding of presumptive intent to kill, not rebutted by the circumstances here.

Several other points raised on this appeal require less extended discussion for their disposition.

Two eyewitnesses, John Eiland and Lee Pharm, testified for the state. The trial court found that the identification of the defendant by these eyewitnesses ". . . was based upon their actual observation of the defendant prior to the time of the assault and their seeing him at the time of the fatal assault and robbery." There is credible evidence to support this trial court finding. Defendant's counsel stresses their distance from the assault (100 feet and 30 feet) and ". . . their preoccupation with other matters at that time. . . ." Neither point is well taken. People are not callous or the sight of an old man being beaten to death so common that the spectacle is unlikely to command the undivided attention of persons standing 30 or 100 feet away. There was in this case a photo-identification of the defendant from police picture files made by one of the eyewitnesses. No objection is raised to it on this appeal. There was also an identification of the defendant by both eyewitnesses of the defendant from a group of 15 to 20 persons of all sizes, shapes and colors crowded into the district attorney's office. No objection was made as to such pretrial identification at the time of trial by trial counsel. It does not remain as a stone for the sling of postconviction counsel. ( See: State v. Cole (1971), 50 Wis.2d 449, 453, 454, 184 N.W.2d 75.)

The defendant's accomplice, Miss Kristy Ruhe, waived her privilege against self-incrimination and testified for the state. On cross-examination she firmly testified that no promises were made to her in connection with her testimony. Defendant's post-trial counsel asks that her testimony be found to be "patently incredible" because of inconsistencies in her recollection of events of the day preceding the murder. There was no confusion shown by her in her testimony that the defendant with her assistance robbed and assaulted the murder victim, and that was the most material portion of her testimony. Credibility was for the trial court to determine ( Gauthier v. State (1965), 28 Wis.2d 412, 137 N.W.2d 101, certiorari denied, 383 U.S. 916, 86 Sup. Ct. 910, 15 L.Ed.2d 671) and the trier of fact was entitled to accept the portions of her testimony that it found credible. ( Embry v. State (1970), 46 Wis.2d 151, 174 N.W.2d 521.) The suggestion that an accomplice's testimony is, by that status alone, rendered incredible is rejected. In this state, even the uncorroborated testimony of an accomplice is competent evidence upon which to base a verdict of guilty. ( Jandrt v. State (1969), 43 Wis.2d 497, 168 N.W.2d 602.) Here it was certainly corroborated. Additionally, defense counsel contends that the failure of the state to have disposed of the charges against the accomplice before defendant was tried renders her testimony "inherently untrustworthy and unreliable." "Viable alternatives" to the procedure followed are suggested by defendant's brief to be either ". . . trying her first or granting immunity to her . . . ." Either of these alternative procedures could have been used, but the state was not required to do other than it did do here. Where charges against an alleged accomplice or codefendant have not been disposed of, such accomplice or codefendant is competent to testify against the defendant, the weight to be given such testimony being in the area of credibility, not admissibility. ( See: 3 Wharton, Criminal Evidence (12th ed.), p. 81, sec. 753; and 23 C.J.S., Criminal Law, p. 65, sec. 804(3)(a)).

After finding the defendant guilty of murder in the first degree, the trial court sentenced him to an indeterminate prison term of not more than thirty years for armed robbery and a consecutive life term for first-degree murder. Defendant's counsel on appeal challenges the imposition of consecutive sentences, noting that "Under the mandatory life sentence for first-degree murder, the defendant is not eligible for conditional parole for at least 11 years, 3 months. . . ." so that "[t]he effect of making the armed robbery sentence consecutive is to add one more year of mandatory imprisonment to his total sentence . . . ." To the frequently expressed strong aversion to interfering with the trial court's area of discretion as to sentencing ( McCleary v. State (1971), 49 Wis.2d 263, 182 N.W.2d 512; Riley v. State (1970), 47 Wis.2d 801, 177 N.W.2d 838), there must be added here complete endorsement of the trial court's comments on the viciousness of the crime and the defendant's willingness to take a human life to obtain money. The imposition of consecutive sentences was done for good reason, clearly stated. The defendant loses one additional year. His victim lost more than that.
