Anne Goff, an 87-year-old retired Sears appliance saleswoman, was found dead in her Coleridge Street home in San Francisco on June 22, 1998. Neighbours and first responders discovered her lying in her bedroom with cuts beneath one eye, cracked eyeglasses on the floor, and her wig discarded in the living room. She had a documented history of congenital heart disease and prescription medication was visible at the scene; the medical examiner initially ruled the death accidental, citing a heart attack and no autopsy was performed before she was cremated.

In early 2003 drifter David W. Silva, then 49 and already serving a life sentence for the 1999 rape-murder of 86-year-old Velma Studendorf, began confessing to additional killings of elderly San Franciscans. Silva described following an elderly woman home, posing at her door about telephone trouble, forcing his way inside and assaulting her; he said the victim suffered a fatal heart attack during the attack and accurately described the displaced wig, body position, and cracked glasses. Authorities reclassified Goff’s death as a homicide and regard Silva as the sole suspect. Prosecutors had not filed new charges for Goff’s killing as of the 2003 disclosure.

Did anyone in the neighbourhood know of unusual visitors to Coleridge Street around June 22, 1998, or have information about Silva’s movements then?
