A man who was beating his girlfriend and then turned on a woman who intervened was shot to death by the second woman early Saturday, deputies said.

Deputies responded to a 911 call at 6 a.m. about a man being shot during an altercation at the Grand Oaks Apartments, 10103 Sherwood Lane, the Hillsborough County Sheriff's Office said.

Deputies said they found Daniel Robertson dead in the parking lot and the two women with facial injuries.

Neighbors said they woke up to screams and shots fired.

"About 6 o'clock in the morning I heard a lady scream, he is killing me, he is killing me," said neighbor Nathanial Taylor.

Before Taylor could rush to help the screams coming from his down stairs neighbor he heard three gun shots.

"One bullet went into the building and then the guy fell here," said Taylor.

Based on preliminary information, deputies said, investigators believe the man forced his way into his girlfriend's apartment and that the second woman, who was visiting her boyfriend next door, went outside after hearing glass breaking and screaming.

The second woman, identified as 51-year-old Vicki Rock, armed with a .45 caliber gun, saw the man beating the first woman with a metal object and yelled at him to stop, deputies said. At that point, according to investigators, the man began attacking the second woman.

She suffered multiple facial injuries before firing at least one round that struck the man, deputies said. The man staggered away and died from his injuries.

Witnesses confirmed statements given by the two women, deputies said. Investigators also found heavy damage to the first woman's front door and window.

Detectives will confer with the Hillsborough County State Attorney's Office to determine whether criminal charges will be filed, the sheriff's office said.
