A 56-year-old Riverview man was shot dead Saturday morning after attacking his girlfriend outside her apartment, the Hillsborough County Sheriff's Office said.
At around 6 a.m., Vickie Rock, 50, of Riverview, was visiting a home at the Grand Oaks Apartments at 10103 Sherwood Lane in Riverview, when she heard glass breaking and screaming coming from next door, deputies said.
Rock, who was armed with a .45 caliber handgun, went outside to investigate and found a Daniel S. Robertson beating his girlfriend, Cristy Vasilakos, 40, with a metal object, deputies said.
Rock yelled at Robertson to stop, but when Robertson turned and began attacking Rock, she fired the gun at least once, deputies said.
Deputies later arrived to discover Robertson dead in the parking lot.
Vasilakos' window and front door were heavily damaged, apparently from Robertson forcing his way into her apartment, deputies said. Both women sustained facial injuries.
Detectives interviewed independent witnesses who, they said, verified statements made by the two women.
Robertson's body will be turned over to the Hillsborough County Medical Examiner to rule on the official cause of death.
Robertson and Vasilakos both live in the complex, in different apartments. Rock was there visiting her boyfriend, according to a news release.
Rock was released Saturday without charges.
Once detectives have wrapped up their investigation, the Hillsborough County State Attorney's Office will determine if charges will be filed at a later date, the sheriff's office said.
