The shooter who killed three people and himself on Menasha’s Trestle Trail last month was drunk when he opened fire. Autopsy results show 27-year-old Sergio Valencia Del Toro had a blood-alcohol level three-times the legal limit to drive, when he rode his bike to the trail on May 3rd.
A detailed report by Menasha police confirmed that Valencia Del Toro had two semi-automatic handguns, and investigators found 18 empty shell casings on the bridge. Valencia Del Toro killed 31-year-old Adam Bentdahl of Appleton, 33-year-old Jon Stoffel of Neenah, and Stoffel’s 11-year-old daughter, Olivia. Erin Stoffel, 32, was hit by three bullets and survived. Valencia Del Toro turned one of his guns on himself.
Police released a 28-page report on the shooting on Thursday. Investigators said Valencia Del Toro got into an argument with his ex-fiancee earlier on the day of the shooting. The report cites a long history of depression, as well as suicidal, and sometimes homicidal thoughts, while Valencia Del Toro was serving in the military.
