Man killed when squad car was rear-ended CHICAGO, Feb. 11 (UPI) -- A man waiting with an Illinois state trooper for a tow truck was killed Saturday morning when another car rear-ended the squad car. The 42-year-old man's car, which was disabled by a previous accident around 1 a.m., was blocking the left lane of eastbound traffic on Interstate 290. A trooper used his car and lights to steer traffic away from the vehicle while the man kept warm in the back of the squad car. Around 1:20 a.m., another car rear-ended the squad car, injuring the trooper and killing the man, the Chicago Tribune reported. The man's family has not been notified of the death. The trooper suffered a concussion and was taken to the nearest hospital. The driver of the other car was also hospitalized; however, the extent of his injuries is unknown. Police are still investigating the crash and have not charged the other driver with any crimes.
