Robinson was driving a bus last month when she found a briefcase. Inside were Hackamack's laptop, wallet, diamond ring and a personal letter from President Obama.
Five days later, Muni officials contacted Hackamack to say they had his bag. He was excited, but turned to ABC7 News to help track down the good Samaritan. That was Kimberly, who returned it with everything still inside.
"I was really glad he got his bag back. I didn't realize how much he had in his bag until he told me. So, I'm glad he got his belongings," Robinson said.
Kimberly says she doesn't deserve all the credit. Another driver who took over her route turned the bag in to lost and found.
