Date Last Seen: February 27, 1989

Background

Sheri Lynn Muhleman was last seen February 27, 1989 at about 9:30 a.m. At that time Sheri was seen by her boyfriend (Michael Abraham) and his sister (Catherine Abraham) at Michael’s house located at 3473 Decoto Rd in Fremont, Ca. Sheri and Michael Abraham had a daughter in common who was five years old at the time of Sheri’s disappearance.

Sheri was last seen packing up her personal belongings inside Michael’s house. Through witness statements, it was believed Michael didn’t trust Sheri to take care of their daughter nor the house while he was gone at a county sponsored Work Furlough Program.

Based on current witness statements and physical evidence located at the Decoto address, it is believed Sheri is a victim of homicide. The whereabouts of Sheri’s body is unknown at this time.
