MARYSVILLE - Snohomish County sheriff's detectives say they believe a late 1992 to 1998 Jeep Grand Cherokee could be the vehicle that struck and killed a Marysville woman whose body was found near Interstate 5 on Wednesday.

The 58-year-old woman was struck sometime early Wednesday morning on 34th Avenue NE on the Tulalip Reservation. The impact knocked the woman out of her shoes and over a wire fence.

She was walking north near the east shoulder of the road when she was struck by a vehicle in the 12400 block. Her body was discovered nearby in a grassy strip between 34th and I-5 by a driver headed south on the freeway.

Evidence gathered at the scene points toward the vehicle being a Jeep Grand Cherokee, said Snohomish County Sheriff spokeswoman Rebecca Hover.

Detectives emphasize that they believe it's a Jeep Grand Cherokee as opposed to just a Jeep Cherokee. The vehicle should have damage to the front passenger side.

The color of the vehicle is not known.

Detectives have determined that a motorcycle and gas can found at the scene did not belong to the woman and are not connected to the incident in any way.

The Sheriff's Office has received some tips on its tip line and detectives are still working to contact those people.

Anyone with information about the incident is asked to call the Snohomish County Sheriff's Office tip line at 425-388-3845.
