October 27, 2006. Sacramento County, California. While performing his overnight patrol duty for the Sacramento County Sheriff’s Department, 38-year old Deputy Sheriff Jeffrey Mitchell sends a message to dispatch that he has pulled over a white Chevrolet van with no plates in a rural area. Minutes later, a clicking noise is heard on the radio and Jeffrey is soon found dead on the ground behind his patrol car, as it turns out he had gotten into a violent struggle before he was shot in the head with his own service revolver. Twelve hours later, a white Chevrolet van containing the bodies of 43-year old Allan Shubert and 28-year old Nicole Welch is found in the Cosumnes River over 20 miles away and it is determined that they succumbed to carbon monoxide poisoning. Over the years, law enforcement explores the possibility that Allan and Nicole’s deaths are connected to Jeffrey’s murder, but no conclusive answers can be found. On this week’s episode of “The Trail Went Cold”, we explore the bizarre murder of a police officer and the deaths of two other potential victims which have gone unsolved for two decades.
So you have any information about this case, please contact the Sacramento County Sheriff’s Department Cold Case Homicide Unit at 916-874-5057 or their tip line at 916-874-TIPS (8477).
