Marion County Sheriff's deputies say a man has killed himself after shooting and killing his ex-girlfriend and her boyfriend at her Silver Spring Shores apartment early Wednesday.

Deputies say 29-year-old Gregory John Briseno killed 26-year-old Alexis Marie Waranka and 30-year-old Ryan Anthony Young at Waranka's apartment at 7417 Midway Terrace.

Deputies responded to the apartment at 4:59 a.m. after someone called 911 and hung up. They found both Waranka and Young dead inside the apartment.

Investigators say Briseno became a prime suspect in the killings after they talked to witnesses and found a Facebook post that included "incriminating statements" and statements that made them concerned for his well-being.

While investigating the apartment, they received a 911 call about a vehicle parked in a wooded area near a business close to 5 Oak Drive in Silver Springs Shores. Deputies arrived and found a red Honda with Briseno inside from a self-inflicted gunshot wound, the sheriff's office says.
