SANFORD, Fla. -

The man who was found guilty of brutally murdering a teen in 2009 requested that he receive the death penalty at a hearing.

William Davis, 33, was convicted of first-degree murder, kidnapping and sexual battery in May in the 2009 death of 19-year-old Fabiana Malave. Davis said on Tuesday that the jury should recommend the death penalty for him and told the jury, "if you recommend life in prison for me, it's a mistake."

Davis said he feels ashamed for killing and raping Malave.

"She doesn't have the opportunity to get married, grow old and have children and grandchildren and that's because of me," Davis said on Tuesday.

Davis met Malave at a Seminole County used car dealership where she worked, abducted her and took her to his Pine Hills home, where he raped her, according to authorities. Davis then strangled the teen and drove around with her body in the trunk of his car, police said.

Davis said on Tuesday he has been convicted of eight felonies and says at an early age he knew he had mental problems. Davis described his relationship with his father as "rocky" and said his dad would "kick the snot out of him" when he was a child.

Davis said he was never suicidal until he was older. He said he was on anti-psychotic medication to keep him from hearing voices and hallucinating. He said he had been off his medication for 13 months when he killed Malave and had stopped taking it because he felt better.

Jurors heard more testimony in the hearing for Davis on Tuesday from Davis' family, with Davis' stepmother, who raised him, offering a statement to the Malave family.

"If there was anything in this world I could do to bring your daughter back I would have done it," Annette Davis said. "If I could have taken her place I would have done it."

Malave's family cried in court on Tuesday after their emotional testimony on Monday.

Malave's sister took the stand on Monday and read a statement about her sister, saying Davis took her sister's dreams away with "his cruelty."

"Fabiana was fragile and easy to get along with," Malave's sister, Wendy Velez, read. "She had no malice, and was trusting of everyone. I can only imagine the shock and fear she must have felt when Mr. Davis terrorized her by forcing her to go with him."

During the trial, Davis' attorneys laid out an insanity defense and told the jury he suffers from mental illnesses. But the state rejected that claim calling Davis a "cold-hearted killer."

Davis' mother testified on Monday via Skype, saying Davis grew up watching his biological father abuse his mother and stepmother.

"He didn't drink a lot, but when he did drink he wasn't very nice," Davis' mother said about Davis' biological father.

The hearing will continue Wednesday with both sides presenting closing arguments, then the jury will deliberate.
