I just got this on my Facebook feed and didn't see a thread/post for her here, so thought I'd start one (apologies if I missed finding an existing one). Excerpts from the Sacramento Police Department's post https://www.facebook.com/Sacramento-Police-Department-137481202396/?fref=nf "Today, January 15, 2016, marks the 35-year anniversary of the unsolved murder of 17-year-old Mary London. On January 14, 1981, Mary London, (pictured) a developmentally disabled student who attended Sacramento High School was reported missing after she failed to show up for a scheduled ride after school. She was last seen near the school at approximately 3:30 p.m. The next morning, (January 15, 1981) Mary’s body was discovered near San Juan Road and Airport Road with multiple stab wounds. To this day, the motive for the murder is unknown. Detectives are asking for the community’s help in identifying a friend of the victim by the name “Darrell.” He is described as a male black adult, who would now be approximately 57-58 years old. Darrell is not a suspect; however detectives would like to speak with him." Anyone with info call: (916) 808-5471, Crime Alert at (916) 443-HELP (4357), or text to 274637 (CRIMES).
