<h1>Truck driver arrested for gross vehicular manslaughter while intoxicated (Pen. Code 191.5) after crash kills three, family disputes impairment</h1> A 21-year-old Indian-origin truck driver has been arrested on suspicion of gross vehicular manslaughter while intoxicated after a Southern California semi-truck crash killed three and injured others; police allege the driver did not brake and toxicology tests showed impairment, while the family denies intoxication and asserts religious and character defenses. Authorities report the driver lacked lawful immigration status and an immigration detainer was lodged; he had earlier been released under an alternatives-to-detention policy. Local community leaders and an advocacy group have demanded investigations into how an undocumented person obtained a commercial license and called for enforcement against human-smuggling and fraudulent migration facilitators.
