McKINNEY (CBSDFW.COM) – One person is dead and four others injured after an early Monday morning crash in McKinney that involved two cars and a street sweeper. Police believe street racing was involved.

The accident happened in front of the Wal-Mart store on Lake Forest Drive, in the “McKinney Ranch” area.

“Two passenger cars, late model Ford Mustangs, were traveling southbound at a high rate of speed,” explained Kim Malolepszy, with the McKinney Police Department.

The ongoing investigation suggests the cars were racing when a street sweeper got in the way. “Both Mustangs struck a street sweeper vehicle that was turning westbound in to the Wal-Mart parking lot, from northbound South Lake Forest Drive,” Malolepszy said.

A passenger in the street sweeper was killed. Of the injured Malolepszy said, “One of the Mustang driver’s was transported to Parkland [Hospital], via CareFlight, the other persons from the accident were transported to Medical City McKinney.”

Investigators say alcohol was most likely involved in the 2 a.m. crash. “There’s evidence that alcohol was a contributing factor, specifically cans of Budweiser beer located at the scene,” Malolepszy said of the evidence.

There’s no word on the medical conditions of those injured and so far no arrests have been made.
