JACKSONVILLE, Fla. -- The attorney of a man accused of killing a 17-year-old at a Baymeadows gas station Friday night said he saw a gun.

Dunn's attorney Robin Lemonidis said Tuesday night that Michael Dunn acted in self defense when he shot and killed Jordan Davis. Dunn, 45, is now behind bars in Duval County.

"He didn't think he had harmed anybody and he just thought he had scared them off and he wanted to report it, but he didn't want to go in a sense, throw himself to the wolves in a strange city without representation," Lemonidis said.

The Jacksonville Sheriff's Office has said Davis was unarmed.

Police extradited Dunn from the Brevard County Jail to the Duval County Jail on Tuesday.

Jail records show Dunn was booked into the Duval County Jail at 2:12 p.m. Tuesday afternoon.

Dunn is accused of killing Davis at the Gate station at Baymeadows Road and Southside Boulevard early Friday evening.

JSO Homicide Lieutenant Rob Schoonover said a car with Jordan Davis and three other teens stopped at the gas station so one of the teens could go into the convenience store.

Schoonover said Dunn and his girlfriend parked next to the teens. Dunn allegedly said something to Davis and the other teens about their music being too loud while Dunn's girlfriend was inside the store.

A verbal altercation ensued between the teens and Dunn. Schoonover said Dunn told police he felt threatened so he shot into the car, firing 8-9 times. Davis was struck twice and died.

Dunn and his girlfriend then left the gas station. The two drove back to Brevard County. Dunn had been visiting Jacksonville to attend his son's wedding Friday night.

Police arrested Dunn at his Satellite Beach home Saturday.

Monday afternoon Dunn pleaded not guilty to charges of murder and attempted murder in Brevard County court.
