According to reports, Beck and his 15-year-old son Stuart were selling the dirt bike to two people in the Belmont Heights section of Tampa during a Craigslist transaction. Police said the Becks quickly realized they were going to be robbed. James Beck was shot as he attempted to leave. His son was not injured.

Stuart Beck mourned the loss of his dad in an interview with WFLA.

"He was a wonderful man," Beck said. "He had a great sense of humor, always knew how to make someone laugh."

The dirt bike had been given to the younger Beck by his father as a Christmas present.

"I worshiped it because it came from my dad," he told WFLA. "He taught me how to ride. It started as his hobby and moved on to mine."

A GoFundMe page was established to raise money for the Beck family.
