Trestle Train Shooter Was Unprovoked

An Appleton man and several members of a Neenah family were the victims of Sunday night’s random shooting on the Trestle Trail in Menasha. Police Chief Tim Styka says when 27-year-old Sergio Valencia del Toro opened fire around 7:30 at least 75 people were in the area. He killed 33-year-old Jonathon Stoffel of Neenah and his 11-year-old daughter Olivia. Stoffel’s 32-year-old wife Erin was also wounded. Thirty-one-year-old Adam Bentdal of Appleton was also shot and killed. Valencia del Toro then turned the gun on himself. Styka says there was no warning before the shooting. He says the shooter shot all four victims unprovoked then turned the gun on himself. Styka says the shooter is from Menasha. He was a UW-Oshkosh student and recently began training as a member of the Menasha Police Auxiliary Unit. He had recently reenlisted in the U.S. Army and was to begin basic training next month. Styka says Valencia del Toro got into an argument with his girlfriend Sunday evening and after she left he grabbed his guns and rode his bike to the Trestle Trail.

Neenah Woman Heroic During Trestle Trail Shooting

Action of a 32-year-old Neenah woman could be termed heroic during Sunday night’s shooting on the Trestle Trail Bridge in Menasha. The head trauma surgeon at Theda Clark Medical Center in Neenah says Erin Stoffel’s actions after she was shot show that you can never underestimate the power of a mother. Doctor Ray Georgen says for her to yell for two of her children to run and get help is incredible. He says it’s an amazing story of heroism on her part and that of her children because notification of people allowed police to get on the scene quickly. John and Erin Stoffel had three children. Their seven-year-old son and five-year-old daughter survived. Georgen says Erin Stoffel is in critical condition. He says she was shot three times, once each in the abdomen, right thigh and left hand.
