A Wyoming man could face decades behind bars if convicted of three felony charges stemming from a 2017 crash that killed a woman and toddler on Highway 220 south of Casper.

Alexander Richardson, 33, of Lusk, is charged with two counts of aggravated vehicular homicide and one count of aggravated assault. If convicted on all three counts, he could face up to 50 years in prison.

Richardson's attorney, Don Fuller, told K2 Radio News that Richardson was driving from his work site in Utah back to his home in Lusk on the afternoon of Aug. 23 when his F-250 collided head-on with a Ford Explorer.

Soonyoung Lee, 46, who had been driving, was killed in the initial collision. Three-year-old Jaehyeok Seo died of his injuries at the scene. One passenger in the Explorer survived and was taken by life flight to Wyoming Medical Center.

First responders pulled Richardson from his pickup truck and took him to Wyoming Medical Center via ambulance.

Assistant District Attorney Michael Schafer told Natrona County Circuit Judge Michael Patchen during Thursday's hearing that the parties had agreed on a $7,500 cash-only bond for Richardson.

Richardson voluntarily turned himself in to law enforcement earlier Thursday, Fuller said.

Fuller, during the hearing, told Patchen that he had expected the charges for the past three months or so. Following the hearing, Fuller told K2 Radio News that he believes the charges to be excessive.

Richardson grew up in Colorado and has lived in Lusk for 17 years, where he has a wife and children. He works as a derrick hand in Utah.

Once released on bond, Richardson will be allowed to travel to Utah and Colorado for work.
