Twenty-two Los Angeles County Sheriff’s Department recruits were injured during a morning run on Wednesday when a wrong-way driver plowed into them near the intersection of Mills Avenue and Telegraph Road, with five reportedly in critical condition, according to ABC7 Eyewitness News. Four of the trainees are being treated for “immediate” injuries and 14 others have minor injuries, according to a member of the Los Angeles County Fire Department. The incident unfolded at 6:29 a.m, when somewhere between 40 and 50 recruits were on a group run through the South Whittier area. A 22-year-old suspect was apprehended, a sheriff’s deputy told the Los Angeles Times, which reported that the condition of the driver prior to the incident was unknown. The car involved, which appeared to be a gray SUV, was left mangled by the incident, with its front end nearly completely obliterated beside a downed light pole. “It does seem like this car did not slow down,” Los Angeles County Supervisor Janice Hahn told KABC-TV. A mass casualty incident has been declared.
