Missing Manteca woman is Tracy homicide victim The body of a woman discovered in an aqueduct near Chrisman Road in Tracy on Monday has been identified as that of Chenin Carlson – the 36-year-old Manteca mother of two that turned up missing over the weekend when she did not report to a new job in Tracy. The announcement of the identification of the body was made Wednesday afternoon by the San Joaquin County Medical Examiner’s Office and came less than a day after the San Joaquin County Sheriff’s Office served a search warrant at Carlson’s home to gather any and all evidence that may point investigators towards what happened to her.
