Any personal property of an inmate which comes into the possession of the Department of Corrections as the result of an escape from a facility of the Department of Corrections or because such property has been left unclaimed by an inmate or individual who has right to its possession, shall be held by the Department of Corrections for a period of ninety (90) days after notice of such possession has been sent to the last known address of the inmate or individual, and a copy of such notice has been posted in a conspicuous location within a public area of the county correctional facility. Personal property being held by the Department of Corrections, if claimed within the period of time referred to in Subsection (a), shall be delivered to the inmate or individual who satisfactorily establishes to the Director a right to its possession and gives a proper receipt therefor. Personal property unclaimed after the period of time referred to in Subsection (a) shall be deemed forfeited and all rights in and to such property shall be foreclosed, extinguished and lost to the owners and claimants. The Director of the Department of Corrections shall transfer to the County Purchasing Agent all property forfeited under this Section. The County Purchasing Agent shall have the same authority with respect to such property as contained in Section 18-115(a) of this Code.
