BLAINE COUNTY — A Fairfield man was in jail Monday after police say he caused a crash early Saturday morning leading to the death of three children east of Hot Springs Landing.

The crash occurred not long after 1 a.m. Saturday, on U.S. Highway 20, according to a Blaine County Sheriff’s Office news release. Somchai Ray Lee Lurak, 26, of Mountain Home, was at the wheel of a 2000 Dodge Neon, with Emma Weigand, 26, also of Mountain Home, in the passenger seat. Also in the car were three children, including 3-year-old Drayka Rayshell, as well as a 5-year-old child and a 6-year-old child. They were not identified in the sheriff’s office post, but according to the Ada County Sheriff’s Office, they were siblings.

Lurak was driving west on Highway 20 and stopped at a construction site. Police believe Matthew Park, 46, then rear-ended the Neon with a 1995 Dodge pickup. They believe Park was intoxicated at the time. According to a criminal complaint filed against Park, his blood-alcohol content was recorded as being between .191 and .189.

The 5-year-old and 6-year-old child died on the scene of the crash, according to an Ada County Coroner’s Office news release. According to the same release, first responders took Drayka to St. Luke’s Regional Medical Center in Boise. She died in the hospital not long after 7 a.m. Saturday, the release said.

Lurak was flown by air ambulance to another hospital and is currently in critical condition, the sheriff’s office release said. The case’s criminal complaint states he had neck and back injuries. Weigund has since been taken to Saint Alphonsus Hospital in Boise for treatment for her injuries, including a fractured arm, according to the criminal complaint in the case.

Park appeared to be uninjured and declined medical help, according to the sheriff’s office. He was arrested on suspicion of two counts of aggravated driving under the influence and three counts of vehicular manslaughter.

The investigation is ongoing, and the Idaho State Police is assisting the Blaine County Sheriff’s Office in reconstructing the accident.
