A Whittier man accused of killing three people in a 2016 street racing crash, including two Santa Clarita teens, was sentenced to 22 years and four months in state prison Friday.

Dealio Lockhart, 38, pleaded guilty to 18 counts: three counts of vehicular manslaughter, four counts of engaging in a vehicle speed contest and 11 counts of assault likely to cause great bodily injury, according to Greg Risling, spokesperson for the Los Angeles District Attorney’s Office.

Lockhart was initially charged with three counts of second-degree murder and four counts of reckless driving causing injury.

On Feb. 27, 2016, around midnight, Lockhart lost control of his Dodge Challenger during a road race on the 5 Freeway and struck a tractor-trailer operated by UPS, the prosecutor said.

The impact caused the big rig to overturn onto the center divider and into oncoming lanes.

The truck’s driver, 52-year-old Scott Treadway, was killed.

The collision involved more than 10 cars near the City of Commerce where Santa Clarita residents and College of the Canyons students Brian Lewandowski, 18, and Michelle Littlefield, 19, were also killed.

In addition to the three fatalities, two men in the Nissan that the students were traveling with were seriously injured and a man and a woman who were in separate cars were also injured, according to Risling.

Both sides of the freeway were shut down the following day as a result of the incident.

Deputy District Attorney Michael Blake of the Target Crimes Division prosecuted the case.
