The San Bruno Police Department announced a breakthrough in a decades-old homicide investigation, identifying the infant found deceased in Buckeye Park more than 40 years ago.

In November 1981, San Bruno police officers were called to Buckeye Park after the remains of an unidentified infant were discovered. Despite an extensive investigation at the time, detectives were unable to determine who the child was or who was responsible for the death. The case remained unsolved for over four decades.

That changed when investigators turned to forensic genetic genealogy, a technology that has helped law enforcement agencies across the country reopen cold cases. Working with the Texas Department of Public Safety, law enforcement forensic partners, and specialized laboratories, San Bruno detectives were able to identify the infant’s family.

“While the police department knows the identity of both parents, their names are not being released at this time,” the San Bruno Police Department said. “This identification represents a major step forward in the case and has renewed efforts to bring this case to justice.”

The department emphasized that the investigation remains active and that public assistance could be crucial in solving the case. Detectives are seeking anyone who may have information about the events that took place in Buckeye Park in November 1981 or who might have knowledge related to the infant or their family.
