FORT MYERS, Fla.- Dylan Wisniewski has been found guilty of manslaughter with a firearm in the shooting death of his girlfriend, Ashlee Swayze, in 2010.

It took the jury less than an hour to deliberate.

Wisniewski tearfully took the stand to defend himself on Friday afternoon. Prosecutors argued that Wisniewski was careless and reckless. The defense said he didn't realize the gun was loaded and that Swayze walked in front of the gun.

The three-day trial was emotional for all involved.

He faces 30 years behind bars.
