Sandy City police and Fire departments work to clean up a serious accident Sunday, Feb. 26, 2012 that took the lives of two men Mark Summerhays 22, and Mike Derby 36. The two were in a MazdaSpeed 6 and tried to make a turn at 8000 south Highpoint parkway 1245 east and collided with a tree the car burst into flame killing both occupants.

SANDY — Two Midvale men were killed early Sunday in a fiery crash that police say was caused by driving too fast.

Police say Marc Summerhays, 22, and Mike Derby, 36, were killed instantly about 3:50 a.m. when Summerhays lost control of the MazdaSpeed6 he was driving and crashed into a tree on the south side of Highpoint Parkway.

"The car literally was split in two," Sandy Police Sgt. Jon Arnold said. "Debris was thrown several hundred feet. It was a severe impact with the tree."

Arnold said a police officer witnessed the Mazda speeding on 7800 South and turned around to follow it. The officer didn't see it again until after it had crashed into the tree and was engulfed in flame, he said.

The charred remains of the Mazda surrounded the tree in a grassy area near 8000 South while crews investigated the accident Sunday morning.

"We have no indication of (reasons for the crash) other than they were driving too fast," Arnold said.

The state medical examiner will determine whether there were any other contributing factors in the crash, he said.

Investigators weren't sure Sunday how fast the car was traveling, though Arnold estimated its speed on the curved, 30 mph road at "well over 60 mph — and probably significantly higher than that."

Arnold called the scene of the accident "as bad as anything I've seen."
