On Tuesday afternoon, October 21, 2025, a tragic incident occurred on the westbound 10 Freeway in Ontario, California, resulting in the loss of three lives. Among the victims were Clarence Nelson, a former assistant basketball coach at Pomona High School, and his wife, Lisa. The couple was traveling together when the collision took place.

The crash involved multiple vehicles, including several semitrucks, and occurred around 1:10 p.m. According to the California Highway Patrol, a 21-year-old semitruck driver failed to brake as traffic slowed, leading to an eight-vehicle pileup. The collision resulted in a fire, with one of the passenger vehicles engulfed in flames. Three individuals were pronounced dead at the scene, and four others were hospitalized. (Los Angeles Times)
The semitruck driver, identified as Jashanpreet Singh of Yuba City, was arrested at the crash site. He faces charges of gross vehicular manslaughter while intoxicated and driving under the influence of drugs causing injury. Authorities allege that Singh was traveling at a high rate of speed and failed to stop in time, causing the chain-reaction crash. Eyewitnesses and dashcam footage have corroborated these claims.

Singh’s immigration status has also come under scrutiny. U.S. Immigration and Customs Enforcement officials issued an arrest detainer for Singh, stating that he entered the U.S. illegally from India in 2022. Despite this, he obtained a commercial driver’s license, which was valid under federal law. California Governor Gavin Newsom’s office clarified that the state does not determine commercial driver’s license eligibility; instead, it is governed by federal regulations. (ABC7 Los Angeles)
