An uncle, Jim DeCarle, said the two had visited the Long Island Sound and the U.S. Open tennis tournament when his nephew was younger. "Those were always some of the best times I had with him," Jim DeCarle said.

In later years, his nephew developed a "fascination" with motorcycles, Jim DeCarle said. David DeCarle's Facebook page features a photograph of a motorcycle and Twisted Sister singer Dee Snider and others in motorcycle gear.

The Riverhead Police Department is investigating the crash and officials said witnesses could call police at 631-727-4500.
