According to police, Raymond Hills, 25, fled from the Elizabeth Township home just after 4:30 a.m. when 84-year-old Fred Ricciutti shot him with the German Luger he used in the Korean War.
"I said 'Halt, who's there?'" said Ricciutti. "I'm thinking, friend or foe, he shouldn't be there that time of day."
Ricciutti said he was awoken when he heard Hiles breaking in through an unlocked kitchen window.
When he confronted the intruder standing in his doorway, Ricciutti fired.
The bullet grazed Hiles in the back of the neck, as well as a door and storm door window.
Ricciutti said he then called police, and Hiles was caught a few blocks away from Ricciutti's home.
According to police, Hiles had a screwdriver and stun gun on him when Elizabeth Township police arrested him.
Officials said Hiles was taken to jail Tuesday wearing a bandage on his neck from the bullet wound.
Authorities said they don't plan on filing any charges against Ricciutti.
