LAWRENCE COUNTY, Pa. -- One home invasion suspect is dead and a second suspect is on the run after breaking into a man's home overnight in Pennsylvania, CBS Pittsburgh reports.

It all started around 1:30 a.m. on Thursday at Don Lutz's home. The 84-year-old, who sleeps with his gun under his pillow, said he was woken up by the sounds of shattering glass and two intruders barging through his front door. He said he got out of bed, and was confronted by one of the suspects.

"Woken up to them busting in on my front door, and I went out in the hallway in the dark, and I met this one guy, and he went to grab me and that's when I shot him," Lutz said.

"Oh yeah, I would have shot him. They dropped the gun out of my hands, it was laying on the floor. I would have shot him, too," Lutz said.
