A 42-year-old woman arrested in the shooting death of a San Francisco teenager might have been dating the high-schooler, according to a local newspaper's report.

According to a press release sent by San Francisco Police Department spokesperson Officer Grace Gatpandan, police believe that Silvia Lorena Montoya (pictured right) shot Jonathan Caballero, an 18-year-old student at Balboa High School, in McLaren Park on May 31, 2015.

Gatpandan wrote that Caballero was found suffering "suffering from an apparent gunshot wound on a walking trail just off John F. Shelley Drive" at 6:45 a.m. that day.

"Officers summoned an ambulance and rendered aid but unfortunately Caballero was pronounced deceased at the scene," Gatpandan writes.

Following a two-month investigation, "San Francisco Police Homicide Investigators developed probable cause to arrest Silvia Lorena Montoya, Hispanic female, 42, of San Francisco," Gatpandan writes.

Just was that probable cause? Well that's an interesting question: in the SF Examiner's coverage of the arrest, they write that Montoya "was possibly dating" her teenaged alleged victim, but did not elaborate or offer any citation for that allegation. (A call from SFist to Gatpandan to confirm that detail has not been returned at publication time.)

The case remains under investigation, Gatpandan writes. She urges anyone with information on the slaying to contact SFPD's Homicide Detail at (415) 553-1145, their Anonymous Tip Line at (415) 575-4444 or to Text a Tip to TIP411, with "SFPD" at the beginning of the message.
