LEE COUNTY, Fla.- The jury has found Kenneth Roop guilty of Second Degree Murder in the 2012 shooting death of a door-to-door meat salesman in Cape Coral.

The defense argued Roop shot Nicholas Rainey out of fear, but the prosecution said Roop shot Rainey twice, in cold blood.

Roop spoke with Cape Coral Police for more than an hour the day of the shooting. This morning, that interview was played for the jury.

Roop decided not to testify, and instead, let the video speak for him. In the video, he doesn't deny that he pulled the trigger, and instead repeatedly says he did it because frightened and didn't want to be in danger.  Also in the video, Roop says his house had been broken into before. So when he pulled up to his home July 25, 2012 and saw a strange man in the driveway quickly walking toward him, he immediately became afraid. He repeatedly said in the video that the person in his driveway, later identified as Rainey, was antagonistic towards him and belligerent.

Roop said he was honorably discharged from the Marines, and used his training to protect himself. But the prosecution said Rainey was simply going door-to-door selling meat and was killed without any kind of warning.
