Shelley Duncanson of Metropolitan Transit said Robert Mader, 55, told officials he was on his way to pick up the wallet about a year ago after leaving it on a bus, but he never arrived and officials were unable to locate him, U-T San Diego reported Thursday.
Duncanson said Mader recently contacted her after an acquaintance read about efforts to locate the wallet owner.
"He remembered losing his wallet, calling us about it and boarding a bus to come pick it up," Duncanson said.
However, Mader suffered the first of a series of strokes on his way to the transit office and spent several weeks in a hospital. She said he had forgotten about retrieving his wallet.
"I'm very sorry about his health issues," Duncanson said, "but I'm happy he got his money back."
