A 17 year old missing persons case from Butte County is being looked again as a possible homicide. It was January of 1996 when Vicki Pyrskalla was reported missing friom West Chico. A woman's body was found soon after that in Yolo County, but it wasn't until authorities matched up Pyrskalla's parents' DNA that they found a connection. Butte County Sheriff's Lt. Al Smith says back in 1996 the technology was not very advanced. He says the official cause of death of the woman in Yolo County is drowning, but there are more questions. Anyone with information regarding this case is urged to contact the Butte County Sheriff's Department.
