Police make arrest in 43 year old San Francisco cold case, authorities say suspect may have killed others

A 15-year-old was murdered while visiting San Francisco more than 40 years ago, and police say they have just arrested the killer.

Mark Stanley Personette was arrested last week in connection to the 1978 death of Marissa Rolf Harvey, according to the San Francisco police and media reports.

Harvey was visiting family in San Francisco from New York when she went to Gold Gate Park on March 12, 1978, according to police. But she never returned home. Her remains were found the next day in Sutro Heights Park, according to KUSA.

Police investigated and the case went cold.

In 2020, the agency reopened the case using new investigative methods and identified Personette as the suspect. Police did not detail how they connected the suspect to the crime.

Personette was arrested in Denver and is currently being held in a Colorado jail.

Detectives say Personette could be involved in other unsolved killings of young women.
