Deputies: Man fatally shoots ex-girlfriend, her boyfriend, then himself

SILVER SPRINGS SHORES, Fla. – A man fatally shot his ex-girlfriend and her boyfriend then killed himself Wednesday morning, according to the Marion County Sheriff's Office.

Deputies said they arrived at a home on the 7400 block of Midway Terrace in Silver Springs Shores after receiving a 911 call from a roommate at the residence who hung up the phone just before 5 a.m. It's not clear why the roommate hung up after hearing gun shots.

Investigators said they found 26-year-old Alexis Marie Waranka and her boyfriend Ryan Anthony Young, 30, dead inside the apartment.

Information from witnesses at the scene led deputies to identify Waranka's ex-boyfriend, 28-year-old Gregory John Briseno, as a suspect in the double homicide. Marion County Sheriff's Office public information officer Lauren Lettelier said Briseno had made incriminating Facebook posts around the time of the killings.

"Because he has made some volatile statements to her In the past, we developed him as a suspect. We found a Facebook post that was quite suspicious this morning on his Facebook page," Lettelier said.

While deputies didn't disclose the exact nature of the post, a search shows that Briseno did make a Facebook status at 4:32 a.m. Wednesday, saying he was "pushed to the limit" and he "will take the title of the bad guy."

"If you are the few who know part of the truth then I know still you won't understand why but just know that I am sorry and had to finish it all once and for all," the post read, in part.

Deputies said that while they were processing the initial crime scene, they received a call in reference to a vehicle parked in a wooded area near a business on Oak Drive. Briseno was found in that vehicle, dead of a self-inflicted gunshot wound four hours after the shooting on Midway Terrace, according to a news release.

Lettelier said that Waranka accused Briseno of domestic abuse earlier this year and although a police report was filed, Waranka chose not to prosecute. 

Records show that incident involved Briseno choking Waranka and pushing her into a wall.

"There were no marks on her for physical abuse, there were no witnesses to corroborate her testimony," Lettelier said.

The families of the victims and the suspect have been notified.

Waranka's family said she was a loving sister and daughter who died too soon.

Deputies said they are no longer seeking any suspects in the crimes.
