ST. PETERSBURG — A 47-year-old woman told authorities her boyfriend assaulted her with a box cutter, so she grabbed a knife and fatally stabbed him Thursday.
Annanay Teaheartt of St. Petersburg faces a second-degree murder charge, St. Petersburg police said.
Officers responded to 3134 Queensboro Ave. S around 1:30 a.m. Teahartt's boyfriend, 45-year-old Demetrius Antonio Burns, had an apparent stab wound. He was taken to Bayfront Medical Center, where he died at 6:42 a.m.
Investigators think Teaheartt and Burns had argued earlier in the night and that a verbal dispute escalated to physical violence.
The couple had a history of legal issues, according to police. Since 2010, Teaheartt had been arrested five times in connection with alleged assaults upon Burns, a St. Petersburg police spokesman said. Three of those cases were classified as felonies.
In December of 2011, Burns faced a felony battery charge for an incident involving Teaheartt, police said.
Teaheartt claimed that Burns hit her Thursday, and police said she had a minor lip injury.
Teahartt told officers that Burns had attacked her with the box cutter outside, so she went inside, grabbed a knife and stabbed him when she was back outside.
No box cutter was found at the scene, police said.
