Wheatley was making a left turn Monday morning about two miles from his home when a UPS truck struck the driver's side of his vehicle, police spokesman Bill Toohey said.
The 48-year-old Wheatley died at the scene. His daughter, who was in the front passenger seat, was taken to a hospital.
Toohey said a traffic light controls the intersection and it appears to be working. Police are investigating to determine whether either driver ran a red light.
Wheatley started at The Sun in 2006 as sports editor. He moved to the business department earlier this year during a newsroom reorganization.
