TECUMSEH, Okla. (AP) - Authorities say a Maud man and his passenger were killed when the pickup truck he was driving collided with a trailer that detached from another vehicle.

The Oklahoma Highway Patrol says 83-year-old Raymond Taylor suffered massive injuries and died at the scene of the accident about 2:15 p.m. yesterday on Oklahoma Highway 9 near Tecumseh.

Troopers say the passenger was 83-year-old Grady Strawn, also of Maud. Strawn was flown by medical helicopter to OU Medical Center in Oklahoma City, where he died from his injuries about 9 p.m.

According to an accident report, Taylor's truck was headed west on the highway and a pickup driven by Darrell Mackey was going east when the trailer attached to Mackey's truck came loose.
