A Perkins man dies in an unrelated crash.

Two men died this week in separate motorcycle crashes, including one in which a man slammed his cycle into the back of a truck on a Tulsa highway at more than 120 mph.

Dead are Brandon Lee White, 26, of Broken Arrow, and Gary Arden Hazelbaker, 62, of Perkins.

The Tulsa collision happened about 1 a.m. Tuesday, Officer Jason Willingham said.

Police said witnesses reported that White's motorcycle appeared to be going at least 120 mph when it crashed into the truck on U.S. 169 south of 81st Street.

Police said the truck driver reported hearing a bump and then seeing debris from the motorcycle going past him. When he managed to pull over, he saw that a man was embedded in the back of his trailer, police said.

White was dead at the scene.

Hazelbaker died Monday afternoon after apparently having a heart attack and crashing his motorcycle about 4:30 p.m. in Payne County.

The cycle ran off Oklahoma 33 about two miles west of Perkins, and Hazelbaker was thrown about six feet, the Oklahoma Highway Patrol reported.

He was taken to the OU Medical Center in Oklahoma City, where he died shortly after 8 p.m., the OHP reported.

Hazelbaker had not been wearing a helmet, troopers said.
