Mother is unsure of actual date, but to her recollection she last saw Louis in 1993 when he exited her vehicle and walked away. Mother thought Louis needed some time to himself and thought he would return home. He never did. I obtained a police dispatch log from Berkeley PD dated 8/25/93 regarding a police contact with Louis for loitering. This is the last known documented stop by police agency. Louis has been missing since 1993.
