A Hammond man died in a single-car wreck in Ponchatoula Saturday, the Tangipahoa Parish Sheriff’s Office said Monday.

Nat John Colona, 45, was driving his 2004 Audi north on North First Street near the intersection of Lavigne Road, where he failed to make a curve, left the roadway and struck a tree sometime before 9:20 p.m., sheriff’s spokeswoman Dawn Panepinto said in a news release.

The Tangipahoa Parish Coroner’s Office pronounced Colona dead at the scene.

Investigators believe he was not wearing his seat belt at the time of the crash. Blood samples were collected, and toxicology results are pending, Panepinto said.
