'Washington's Most Wanted' profiles Marysville woman missing since 1997
MARYSVILLE — Lisa Sledge's family reported her as a missing person on Dec. 12, 1997, and at 10:30 p.m. on June 17 and 18, "Washington's Most Wanted" on Q13 will be covering her case.
The Marysville mother's disappearance more than 13 years ago is one of only three unsolved cases in the Marysville Police Department. She was reportedly last seen alive with her boyfriend at the time, Erick Mattison, on the Tulalip Indian Reservation on her 28th birthday on Dec. 8, 1997.
Sledge's mother, Betty Price, passed away without ever knowing what happened to her daughter. Sledge's father, Randy Price, took on the responsibility of raising Lisa's son and daughter. Lisa's parents knew she'd started using illegal drugs before her disappearance, and she was scheduled to go into treatment in January of 1998.
According to Mattison, Sledge walked off after the pickup truck they were in got stuck in the mud. In his account, Mattison and Sledge got into an argument, Sledge left and Mattison got the truck unstuck with the help of some friends.
Marysville police have received more than 100 tips in this case, and one of the most common rumors reported to them is that Sledge died of a drug overdose. While these rumors vary in where this occurred, who was involved and where Sledge is now, a common claim of the rumors is that those persons with Sledge at the time of her overdose panicked and buried her remains without contacting authorities.
Marysville Police Detective Cori Shackleton explained that the statute of limitations has long since run out on any charges of controlled substance homicide, mishandling of human remains, and obstructing or rendering justice, so if Sledge did die of an accidental overdose, any persons involved can come forward without being arrested or charged with any of those crimes.
