CAPE CORAL, Fla.- New developments in the shooting death of a Cape Coral teenager. 15-year old Ashlee Swazey's boyfriend is now behind bars and facing charges of manslaughter.

Dylan Wisniewski is currently being held at the Lee County jail. Investigators say he pointed a rifle at his girlfriend, and pulled the trigger. Wisniewski claims he didn't know the gun was loaded, that it was a prank gone terribly wrong.

"He's a good kid. This kinda thing doesn't happen to good kids. But I guess it does," neighbor Cullen Lowe said Saturday.

Friends of Dylan Wisniewski are shocked, after a seemingly normal neighborhood was shattered in the pull of a trigger.

"About 12 cops, ambulance, you name it. We had everybody here," neighbor Randy Ashby said.

Investigators swarmed Dylan's home on Friday, after they say he shot his girlfriend Ashlee in the head with a .22-caliber rifle.

"He said it was an accident. I would take him at his word. If he said it was an accident, it probably was an accident," Lowe said.

Even so, it's an accident now landing the 18-year old behind bars. Dylan's being charged with second-degree manslaughter, which carries a maximum sentence of 15 years in prison. But those who knew Dylan and Ashlee say they were two teenagers in love. She'd ride her bike to the his house almost every day.

"She would come over, and they would spend the day together and in the evening he would go with her halfway home so that she would get home ok. You know, typical teenagers that like each other," Lowe said.

Cape Coral Police Department continues to investigate the crime. In the meantime, grief counslers will be available next week at Ida Baker High School where Ashlee was a student, offering comfort to those devastated by a life ended tragically too soon.

"It's sad. A little kid like that. I seen her, only on her bike," Ashby said.

Wisniewski went before a judge for his first appearance early Saturday morning. He's being held on no bond at this point in time.
