The 83-year-old retired seamstress, identified only as Birgitta, had for years kept her savings in a desk in her home in Gothenburg in western Sweden.
The elderly woman finally decided it would be safer to put the cash in a bank account, the Aftonbladet daily reported.
On February 19th, she filled a paper bag to the brim with 10,000-kronor piles of bank notes before taking a tram to the centre of town.
“I was going to the bank to deposit the money,” she told the paper.
But when she got to her stop, she forgot the bag and got off leaving her life savings behind.
Birgitta was too embarrassed to tell her family what had happened at first, and when they finally contacted the tram operator the money was long gone.
“I don’t think there is a chance I’ll get the money back, but if someone does return it they will of course receive a finder’s fee,” she told Aftonbladet.
Gothenburg police were more optimistic however, pointing out that surveillance cameras on the tram could help them identify who had taken the bag of money.
