Amanda Stavik in 1989

WHATCOM — ABC 20/20 will internationally air a two-hour special titled  “30 Years Searching,” chronicling the investigation into the 1989 local murder of Amanda T. “Mandy” Stavik and the resulting prosecution of Timothy Forrest Bass this year. 

The program is scheduled to air at 9 p.m. PST Friday, Sept. 20, on ABC affiliates including station KOMO-4 of Seattle.

ABC has put out a 2:43-minute trailer highlighting what the full special will be about. 

On Nov. 24, 1989, Stavik, 18, a Mount Baker High School graduate, disappeared while out jogging with the family dog in the Nooksack River South Fork area of Whatcom County. Her nude body was found in the river three days later, and she had been raped. The dramatic crime case went cold across 29 years until a DNA match pointed to Bass, now 51, who had lived near Stavik at the time of her death. He also had continued to live in Whatcom County and have a family.

A Superior Court jury in May convicted Bass of the Stavik killing. He was sentenced by  Whatcom County Superior Court Judge Robert Olson to 320 months in prison, the maximum sentence of just under 27 years, in July. 

Whatcom County Sheriff Elfo had this to say in anticipation of the airing: “We appreciate 20/20’s work on this production which will depict how good citizens came forward to help law enforcement solve this horrendous case of kidnapping, rape and murder. My hope is that it will motivate people who may have suspicions about other cold case murders here or elsewhere to come forward and provide information to law enforcement.

 “While Mandy will not have justice in this life, we hope that the work of our detectives and prosecutors will help bring some comfort to her family.”
