Cal. Pen. Code § 5062
Whenever any person confined in any state institution subject to the jurisdiction of the Director of Corrections escapes, or is discharged or paroled from that institution, and any personal funds or property of that person remains in the hands of the Director of Corrections, and no demand is made upon the director by the owner of the funds or property or his or her legally appointed representative, all money and other intangible personal property of the person, other than deeds, contracts, or assignments, remaining in the custody or possession of the director shall be held by him or her for a period of three years from the date of that escape, discharge, or parole, for the benefit of that person or his or her successors in interest.
Upon the expiration of the three-year period, any money and other intangible personal property, other than deeds, contracts, or assignments, remaining unclaimed in the custody or possession of the director shall be subject to Article 1 (commencing with Section 1500) of Chapter 7 of Title 10 of Part 3 of the Code of Civil Procedure.
Upon the expiration of one year from the date of that escape, discharge, or parole:
If any tangible personal property covered by this section is not salable at public auction or upon a sealed-bid basis, or if it has no intrinsic value, or if its value is not sufficient to justify its retention by the director to be offered for sale at public auction or upon a sealed-bid basis at a later date, the director may order it destroyed.
