TAMPA — Police continue to investigate a Saturday home invasion where the suspect was shot in the head with his own gun after a struggle with his victim.

Leonard Denard Porter, 34, of Tampa remained in critical condition Sunday at St. Joseph's Hospital. Police have released no new information in the case.

Around 2:30 a.m. Saturday, Porter broke into Teresa Martin's house, pointed a gun at her and demanded cash, police said.

Martin, 50, said when she informed him that she didn't have any, Porter forced her onto her stomach on the bed. She struggled, and during the fight, Porter's gun went off and he was shot in the head, she said.

After the gun went off, Martin ran to the living room and woke up a friend who was sleeping on the couch, Jerry Bullard, 52.

Bullard called the police.

Porter, who also goes by the alias "Kool Aid," was already sought in another home invasion, police said.

Two others were also arrested in connection with the home invasion, although police have not provided information about their alleged roles.

Johnny Acevedo Jr., 31, and Audra Noel Steadman, 30, both of Tampa, were charged with home invasion robbery, robbery of less than $300 and armed burglary with assault and battery.

Martin said she knows Acevedo so well she considers him like family. Martin said she had never seen Porter before.

Both Acevedo and Steadman have been arrested several times, and Acevedo was sentenced to four years of probation for a drug possession charge in May, state records show.

That history didn't strain his relationship with Martin, who has a lengthy arrest record as well that includes drug and theft charges. She said Acevedo knew about her finances and when her government checks arrive.

Acevedo and Steadman are being held without bail in the Hillsborough County jail.
