SAN FRANCISCO (CBS SF) - A search of a Haight-Ashbury home Tuesday investigating the 1984 disappearance of 10-year-old Kevin Collins uncovered bones under the home's garage, but initial assessments by the medical examiner's office indicates that the bones are from an animal, police said.
The search warrant was served Tuesday morning in the 1100 block of Masonic Street following up on the nearly three-decade old cold case in which the missing boy vanished from a San Francisco street.
Collins' mother, Ann Deasy Collins, confirmed to CBS 5 that she was contacted by police about the discovery of bones at the residence. Her son was last seen on February 10, 1984 - just a block from the search site at Page Street and Masonic Avenue. Kevin Collins' disappearance on the way home from school sparked a high-profile nationwide search and increased awareness of missing children.
The FBI and cadaver dogs from the Alameda County Sheriff's Office assisted in the search, and the dogs indicated that there were possible remains under the concrete floor of the home's garage.
The concrete was removed and several bones were located and turned over to the San Francisco medical examiner's office. Police said that a preliminary assessment of the bones indicates that they are from an animal, but that further analysis is necessary.
San Francisco Home Searched In Connection With Cold Case
Police said that the home's current residents are not suspects in the disappearance.
The search warrant remains sealed and the investigation is ongoing, according to police.
A neighbor who declined to give her name said police had been coming and going all day and were digging at a property nearby.
Arthur Wentworth, who lives next door to the home where the search warrant was served, said authorities had told neighbors they were serving a search warrant but gave no other details.
He said there had been police activity at the home since Tuesday morning, and that he had heard drilling and seen men wearing hardhats.
As of 6 p.m. Tuesday, most of Masonic Street remained blocked off and police continued their investigation at the home.
