Brennan Breene of Bridgeville said he was driving home Sunday when he discovered the envelope in the middle of the road and he checked local news sites for reports of missing cash, the Pittsburgh Post-Gazette reported Tuesday.
Breene learned newlyweds David and Ashley Marasco had lost the money while driving away from their wedding reception. Ashley Marasco said a motorist at a stop light informed her that the wedding album was on the trunk of their car, but the envelope had since apparently flown away.
"I come from a big Irish Catholic family and my parents kind of instilled in us to do the right thing," Breene said.
He said he immediately took the money to the Bridgeport police station.
"To be quite honest with you, I would have loved to have had $3,600," he said. "But my better conscience said it wasn't mine."
