Skull Identified as Possible Green River Victim

A skull found in an Auburn ravine on Tuesday (December 21st) was positively identified as Becky Marrero. The remains were identified by Dr. Gary Bell, who performs forensic odontology for Medical Examiner’s Office and the Washington State Patrol Crime Lab.

Detectives believe Marrero was very likely a victim of serial killer Gary Ridgway, the so-called Green River Killer.

Marrero was last seen on December 3, 1982 when she left a motel room at S. 168th and Pacific Highway South. She was 20 years old at the time.

Marrero was reported missing to the Sheriff's Office by her mother on July 20, 1984. Her disappearance was investigated by the Green River Task Force, and she was believed to be a Green River victim.

Ridgway was arrested on November 30, 2001. Two years later he pled guilty to the murder of 48 women and was sentenced to 48 consecutive life terms. He was not charged in the Marrero case.

The remains of Marie Malvar were found on September 28, 2003 in the same general area where Marrero was found. Malvar was last seen in 1983 at S. 216th and Pacific Highway South. Ridgway was convicted in the Malvar homicide.

Ridgway was questioned extensively in 2003 about Becky Marrero’s disappearance. However by policy, the Sheriff's Office does not discuss what suspects say or don’t say during the investigation of open cases.
