Mark Conroy, 60, of Marietta, a retired Hewlett Packard employee, was riding his Honda Gold Wing motorcycle southbound on Johnson Ferry Road, just north of Willows Way not far from Post Oak Tritt Road, when the truck cut in front of him.
Conroy was in the right-hand lane and investigators believe he was forced over the curb, where he struck a brick pillar of a wood fence. The crash happened about 4:45 p.m. Wednesday.
Witnesses said the driver of the pickup truck may have cut in front of Conroy to go around another vehicle in the left-hand lane, though the truck did not hit the motorcycle, Cobb Sgt. Dana Pierce said. The truck had a University of Georgia insignia in the back window, he said.
"You know sometimes how you look over your shoulder and go, 'I can make that change,' when there is a vehicle in the slow lane and one in front of you are close together. Next thing you know, you jerk the wheel and shift on over. That is what witnesses said it looked like the driver of the truck did," Pierce said.
Becky Conroy said Thursday that she is devastated by her husband's death. He was the father of two adult daughters who live in Marietta and Hurst, Texas, and the grandfather of three.
Any driver who is aware of a crash is obligated by Georgia law to stop and render aid and/or notify authorities, Pierce said.
