FORT MYERS, Fla.- A Lee County teenager was sentenced to 3 years in prison and 3 years probation for killing his father at a Tampa area hotel last year.

Brandon Davis plead guilty to manslaughter in a Tampa area courtroom on Monday.

Authorities say he shot his father multiple times, after witnessing a violent fight between his parents.

The family was on vacation at the Holiday Inn Harbourside in April 2011 when the shooting happened.

The 19-year-old's mother says, "my son was in fear for me and himself and I think what they handed him yesterday was extremely unjust."

Dana Davis says her son saved her life that day. She now lives in Talahassee. She says, "he seems to be holding up well, Brandon's a strong kid. I'm extremely proud of him and everything he's been through."

His attorney, Joe Viacava, says, "it was a complete tragedy, basically the testimony was, there were many years of abuse and all kinds of problems between the mother and father and Brandon and basically he felt he had no other decision but to protect himself and his mother by using deadly force."

He adds, "his father was basically having a savage fight with not only his mother but with Brandon as well and he just wanted it to stop. And when his father saw the firearm he reacted very aggressively."

Viacava says he requested the judge treat Davis as a youthful offender, allowing the court more leeway with his sentence.

He says, "in this case we had a decision to make, and we did not feel we had a good enough defense to go to trail, so we basically left it up to the judge to determine the sentence."

He says the outcome could have been worse, "I think one of the biggest tragedies and the lesson to be learned from this case is anybody who is in that cycle of domestic violence, there is help out there and please don't feel there is no where to go."

But for Dana Davis, any jail time for her son is too much. "Yesterday was worse than the whole experience," she says.

She adds, "I miss my kid. But we'll be ok. We're safe." Of her late husband, she says, "I wish things were different."

Viacava says he expects Davis to just serve two years in jail. He says he was recently accepted to Florida State University, and plans to attend when he gets out of jail.
