ORLAND PARK, Ill. (AP) — A suburban Chicago man thought the errant nail that discharged from the gun he was working with had whizzed by his head. Instead, it was lodged in his brain.

Family members say Dante Autullo spent more than a day with the 3½-inch nail in his head before having it removed Thursday.

The 32-year-old was tinkering in the garage of his Orland Park home Tuesday when then the nail gun went off. He saw a small wound but couldn’t find the nail and didn’t think much of it.

He went to work the next day but later went to the hospital with nausea and one monster of a headache.

That’s when an X-ray uncovered the nail.

Autullo is recovering after a four-hour surgery to have the nail removed.
