Toxicology report: Teens in summer fatal crash in Delafield had been drinking
Speed major factor in crash
Toxicology reports and the final collision analysis and reconstruction report done by the state patrol show that alcohol and speed played a major part in the crash that killed three Arrowhead High School students this summer in the City of Delafield.
City of Delafield Police Chief Scott Taubel said Kody Koepke, the driver of the 2005 Chevy Cobalt that crashed into a utility pole at 3:13 a.m. July 24 on Nagawicka Road, just north of Faire Lakes Parkway, had a 0.175 blood-alcohol level.
Timothy "TJ" Peters, the front-seat passenger, had a blood-alcohol level of 0.115.
A reading of 0.08 is considered evidence of drunken driving in adult drivers in Wisconsin. Koepke and Peters, who were both 18, were both younger than the legal drinking age. Drivers younger than 21 are required by law to maintain "absolute sobriety."
Taubel said the reports said no other drugs were found in their systems.
Koepke and Peters, 2012 Arrowhead High School graduates, died at the scene from head trauma, while Ian Glidden, the back-seat passenger, died from head trauma after being transported to Froedtert Hospital.
The police chief added that because a blood test was administrated after Glidden had been in the hospital for a while, a correct BAC was not possible.
According to the final accident report, the vehicle was going 58 mph when it struck a utility pole.
The report says the vehicle’s speed was 74 mph five seconds before impact, and the speed of the vehicle when it began leaving tire marks on Nagawicka Road was between 65 and 68 mph.
The posted speed limit at the crash scene is 30 mph. There is a cautionary curve ahead sign for 25 mph speed for traffic northbound on Nagawicka Road.
The report added that no highway, environmental or vehicle factors have been identified as factors in the collision.
Koepke, of Hartland, and Peters, of Pewaukee, were wearing their seat belts. Glidden, of Nashotah, was not wearing his seat belt.
Glidden would have been a senior at Arrowhead High School this fall.
