Lynne Gramling, president of Central Contractors' Supply Co., tells the Johnstown Tribune-Democrat that the check arrived earlier this month.
It included an anonymous letter that says the writer stole a hammer 25 to 30 years ago. It reads, "Enclosed is $45 to cover the hammer plus a little extra for interest. I'm sorry I stole it, but have changed my ways."
Gramling is donating the money to the Salvation Army.
As for the check, she wants the sender to know: "It was a gift from the heart and I appreciated it."
