WEST PALM BEACH, Fla. (AP) - A 19-year-old convicted of first-degree murder in the death of a rising Pahokee football player has been sentenced to life in prison.

A West Palm Beach judge imposed the mandatory sentence Friday for Carl Booth Jr., who was 17 years old at the time of the shooting.

Booth apologized to the victim's family, saying he never intended to hurt his friend.

Police say 18-year-old Norman Griffith Jr. was shot in the head after a post-game dance in 2008. A reputed gang member told detectives he saw another person fire the shot. But that murder case was later dropped.

Booth's defense attorney plans to appeal the conviction. Kelly Landers says jurors should have heard about the other teens involved that night.
