Coconino County Sheriff detectives are investigating a stabbing and a traffic accident that are connected. Deputies and DPS state troopers responded to a call Wednesday night at around 8:26 p.m. near the intersection of Interstate-17 and McConnell Drive. One of the people who called 911 to report the incident told dispatch that a white truck that was involved in the accident left the scene. The caller also reported there was a male at the scene who told them he had been stabbed and was riding in the truck. He was taken to Flagstaff Medical Center for treatment. Later in the evening, deputies were called on a welfare check to a house in Winona. When deputies arrived, they saw a truck with front-end damage and blood inside. A man at the residence told deputies he met two other men at a local bar and they returned to his house to drink. At some point, the two other males got into an argument and one of the men stabbed the other. The homeowner attempted to take the victim to the hospital, but was involved in the accident. Arrested was 61-year-old David Slater of Anthem and was booked on two counts of aggravated assault. The incident remains under investigation.
