A Colorado man who bolted from a minor traffic stop and was fatally struck by a car on a highway had been jolted with a police officer’s stun gun, a “criminal and reprehensible” action that left the man lying prone in the road while high-speed traffic approached, lawyers for the man’s family said Wednesday.

The Larimer County Sheriff’s Office released video of the Feb. 18 incident and it shows officers chasing Brent Thompson, 28, running toward Interstate 25 in Northern Colorado. It cuts off before Thompson is struck by the car.

But the law firm representing Thompson’s family released a lengthier video Wednesday that shows much more graphic and troubling footage, including Thompson lying immobilized on the highway after being stunned, with a wire from the stun gun still attached to his body as a car traveling at least 40 mph approached. One of the sheriff’s officers is heard on video saying, “s—t, s—t,” moments before Thompson is run over.

“The tasering of an individual in the middle of an interstate highway at night is criminal andreprehensible conduct and has no place in law enforcement, a statement from the law firm of Rathod Mohamedbhai said.

The body-worn camera footage depicts Deputy Lorenzo Lujan using the stun weapon on Thompson. He was shocked on the interstate 5.6 seconds before a car hit him, an investigation found.

Thompson died at a nearby hospital from his injuries, less than an hour after the traffic stop. Local prosecutors have declined to charge Lujan criminally, but District Attorney Gordon McLaughlin said Lujan’s actions show “poor judgment and possibly a need for additional and more robust training.” McLaughlin said he felt Lujan actions stopped short of “criminal culpability.”

Lujan was put on paid administrative leave following the incident and returned to work early July in a non-enforcement capacity while waiting for an investigation to finish, Larimer County Sheriff John Feyen told the Coloradoan, part of the USA TODAY Network. He remains employed as a deputy.
