Helen Milligan of Drexel Hill said she does not know if the trombone belonging to her son, Aidan, was stolen or picked up as trash Thursday, but she received word Sunday that a man had turned the missing instrument in to the Philadelphia Police Department, the Philadelphia Inquirer reported Monday.
"I'm just overjoyed. I'm delighted," Milligan said. "I don't think anybody ever thought we were going to see that trombone again. So whoever turned that in, I give him a lot of credit."
Milligan said the Philadelphia Orchestra had offered to replace the trombone if it did not turn up.
"I said to them, 'Don't go through with anything, because you never know. Someone might turn it in,'" she said. "I thought there was a small chance, but I didn't really think it was going to happen."
Milligan said police told her the man who turned in the instrument did not have a criminal record and they are unsure of whether the trombone was stolen.
"We're not going to ask any questions or anything. We're just glad to have the trombone back," she said. "I just say, 'You know what? I'm just happy he turned it in.'"
