 By the time the gunman shot himself, Jonathan Stoffel, 33, of Neenah, and his 11-year-old daughter, Olivia Stoffel, were dead in what police called a random attack. Another man, Adam Bentdahl, 31, of Appleton, was also killed in the attack Sunday in Menasha, a community of around 17,000 about 30 miles south of Green Bay. Aaron Zemlock, Menasha's community liaison officer, said police don't know a lot about Bentdahl. Police identified the gunman as 27-year-old military veteran Sergio Daniel Valencia del Toro, and said he apparently was upset over a fight with his ex-fiancee earlier in the day. He was a second-semester freshman at the University of Wisconsin-Oshkosh, studying criminal justice. A U.S. Army spokesman said he joined the Michigan National Guard after he left the Air Force in March 2014. Air Force records show that Valencia del Toro was a senior airman when he was discharged from the service in 2014. Campbell said Olivia was a bright child who loved her siblings and nature. Stoffel's wife, Erin Stoffel, 32, was struck three times but survived, guiding her other two children, ages 5 and 7, off the bridge and sending the older one for help. "Our prayers go out to the other family who lost their father and daughter, and mother who is struggling for life along with the man who took his own life," they said in a statement. She said she's in a state of disbelief. Family and friends of the Stoffel family gathered for a prayer ceremony Monday at Calvary Bible Church in Neenah. The chief said Valencia del Toro shot the Stoffels and Bentdahl with the pistol and then shot himself with the revolver. Olivia Stoffel attended fifth grade at Fox Valley Christian Academy, which is attached to the church. The shooting spree took place on the west end of the bridge that spans Little Lake Butte des Morts and connects Menasha and the Town of Menasha.
– A little boy who went out for a bike ride with his family in Menasha, Wis., ended up running to save his mother's life after a stranger opened fire on Sunday, police say. After Sergio Daniel Valencia del Toro, a 27-year-old man apparently upset by the end of a relationship, started shooting on the Fox Cities Trestle Trail Bridge, wounded mom Erin Stoffel managed to get her son Ezra, 7, and daughter Selah, 5, off the bridge and told Ezra to run for help, the Post-Crescent reports. The boy met an unidentified man who called for help. "It was a little boy who helped save his mother's life," the coroner says. Stoffel was shot three times in the attack; her husband, Johnathon, and 11-year-old daughter, Olivia, were killed. "You can never underestimate the power of a mother to protect her children," the director of trauma services for Theda Clark Medical Center tells the Post-Crescent. "To have three gunshot wounds and be able to get off that bridge and save two of her children is incredible. It's an amazing story of heroism on her part and certainly of her children." Another man, 31-year-old Adam Bentdahl, was killed in the attack, and police say he also appears to have simply been in the wrong place at the wrong time, the AP reports. Police say that Valencia del Toro, an Air Force veteran who recently enlisted in the US Army, opened fire unprovoked and at close range before fatally shooting himself, the Post-Crescent reports. He had been in a fight with his ex-fiancee earlier in the day.
