Police announced Thursday the first two homicide arrests of 2008 by the Jacksonville Sheriff's Office: Quentin Joyner was charged with Monday night's shooting death of 21-year-old Kevin Jackson, and Erica Thomas, 19, was charged in the shooting death of a man during a robbery at a Westside motel in October.

According to the arrest report, Joyner was fighting with Jackson Monday night at the Sanctuary Walk Apartments before he went to his car, got a handgun, returned and fired shots through the door.

Witnesses said Jackson jumped from a second-story window and began to run away while Joyner gave chase and fatally shot the 21-year-old.

In addition to a charge of murder, Joyner is also charged with possession of a firearm by a convicted felon.

Police said they began building a case against Thomas in the Oct. 2 homicide of 54-year-old Jimmy Daugherty, of Kingsland, Ga., after getting a tip from the teen's friend.

Detectives provided the friend with a recording device and they said she recorded Thomas admitting she planned to rob the victim in a Lane Avenue motel room, but the robbery "went so south."

Thomas was a student at Raines High School at the time of the crime, which detectives said she had planned for two months.
