A 50-year-old man is in custody in connection with the death of his 19-year-old girlfriend Saturday, however it remains unclear how the woman died.

The victim’s live-in boyfriend, Tony Evans Taylor, was arrested on an outstanding warrant shortly after the incident was reported, however detectives plan to file murder charges against him.

The dead woman’s name was not released pending notification of next-of-kin.

Deputies found the woman injured from a fall from a second-story window outside her home in the 2400 block of Lincoln Avenue shortly after 5:30 p.m. Saturday.

A witness reported hearing what sounded like a gunshot around the time of the incident, but doctor’s could not confirm Sunday if the woman had been shot. The coroner’s office will make that determination following an autopsy.

The victim died at a local hospital shortly after the incident.

Detectives learned the couple apparently had a history of domestic violence prior to the incident, which went largely unreported to authorities.

The warrant Taylor was initially arrested on was believed to be for making terrorist threats against the victim.
