INDEX — A driver who allegedly struck and killed a pedestrian in Index in August, then left the scene told police she thought she’d hit a dog.

Before the woman met with the detectives nine days later, she hired a lawyer and took her 2006 Hyundai Sonata through a car wash twice, according to the police report.

The victim’s blood still was found on her car.

The Aug. 4 accident took the life of Stacey Lain Broyles, 47, of Index. Investigators believe that Broyles was drunk and lying in the road when he was hit. His dog also died from injuries sustained in the accident.

The case now is awaiting review by Snohomish County prosecutors.

The woman, 49, of Everett, reportedly told police she saw only the dog and a backpack.

She said she saw the dog sitting in the road and swerved but was unable to avoid the animal. She said she stopped, turned around and saw the dog but kept going to get help.

Another person in the area reported seeing a man’s body at the edge of the road a short time later and called 911.

The woman’s lawyer arranged her meeting with detectives. She reportedly had been drinking alcohol in violation of a court order. She told investigators about another vehicle that had been speeding in the area about the time of Broyles’ death.

The Herald is not naming the woman because she has not been charged in connection with the crash. She has no known felony history.

Reports filed by Snohomish County sheriff’s detective Joe Goffin show that laboratory test results from the Hyundai’s undercarriage didn’t come back until November 2012. Additional results came back in mid-March.

The tests showed that Broyles’ blood was found on the Hyundai’s undercarriage and engine. The DNA match was calculated at 1 in 4.3 quintillion.

Police believe that evening Broyles and the woman had both attended the Index Arts Festival. At some point, the woman drove to a home where she was staying nearby and then headed to town. After the crash, she drove back to the house.

She and her boyfriend reportedly talked with friends and neighbors, at least one of whom was a firefighter who already was headed to the collision scene. The couple had left their young children alone at home and didn’t go back to the scene because they knew others were going to help the dog, the woman told police.

Police say Broyles’ injuries were consistent with the woman’s description of how her vehicle struck the dog. Autopsy results also showed the man had multiple broken ribs and other bones but no fractures to his pelvis or legs.

Investigators believe the pattern of his injuries and the damage to the car show that Broyles was lying down at the time of impact.
