Investigators continue to gather evidence as they piece together what they believe was an intentional head on fatal collision between a pickup truck and motorcycle in Fond du Lac. The crash happened shortly before 7pm Friday near the intersection of Winnebago Drive and Taycheeda Way. Fond du Lac County Sheriff Ryan Waldschmidt says based on evidence at the scene and statements made by various individuals investigators believe 27 year old Daniel Navarro of Fond du Lac intentionally veered into the oncoming lane of traffic striking a motorcycle head on, killing the motorcycle operator, 55 year old Phillip Theissen of Fond du lac. Waldschmidt says investigators continue to gather evidence, tracing where Navarro was driving and his driving pattern prior to the crash. “There’s a lot of things we’re following up on, a lot of information we’re gathering,” Waldschmidt told WFDL news. “We’re canvassing the neighborhood in that area and the general stretch of Winnebago Drive from the point of that crash backward into the city of Fond du Lac. We’re talking to residents, businesses that might have camera systems working on gathering evidence.” Waldschmidt says investigators believe they have an idea what the motive may be, but says that information will come out when the criminal complaint is made public. Waldschmidt says investigators do not believe the suspect and victim knew one another or that Navarro was aware that Theissen had retired recently as a police officer in Virginia before moving back to Fond du Lac. Theissen was a 1983 graduate of Fond du Lac’s Goodrich High School. Navarro is being held in the Fond du Lac County Jail on suspicion of first degree intentional homicide.
