A routine traffic stop reunited a New Jersey state trooper with the now-retired police officer who helped his mother deliver him as an infant.

Trooper Michael Patterson was on patrol Friday when he pulled over Matthew Bailly for a tinted window violation in Kingwood Township. The two men talked and Bailly mentioned he used to be a police officer in Piscataway where Patterson grew up.

Bailly was on duty in Piscataway 27 years ago when he was called to the home of Karen Patterson, who had gone into labor.

“He goes so far as describing the house that I grew up in, and then he said, ‘The baby's name was Michael.’ How he remembered that, I don't know,” Patterson says. “So I extended my hand and I said, 'Sir, my name is Michael Patterson. Thank you for helping to deliver me.’”

New Jersey State Police said Wednesday that Bailly wasn't ticketed. The trooper and his mom later met Bailly and his wife.

Patterson says that every year on his birthday his mother retells the story of the officer who helped to deliver him as a baby.
