11-year-old girl among those killed in 'random' shooting on popular Wisconsin bridge

A popular destination for walkers, joggers and fishermen in eastern Wisconsin, the scenic Fox Cities Trestle Trail pedestrian bridge, is now a crime scene following a shooting that left four people dead, including an 11-year-old girl.

Police said the 27-year-old gunman shot four people – killing three of them – before turning the gun on himself in what has been described as a random act of violence Sunday evening.

At a news conference Monday, the Menasha police chief Tim Styka identified the victims who were killed, including 33-year-old Jonathan Stoffel, his 11-year-old daughter Oliva, and 31-year-old Adam Bentdahl, Post-Crescent Media says.

Stoffel's wife, Erin Stoffel, underwent surgery and was listed in critical condition Monday.

Officials said the shooter, who they identified as Sergio Daniel Valencia del Toro, had "relationship issues," noting he and his fiancee had recently called off their wedding.

Police say the suspect was a student at the University of Wisconsin-Oshkosh, a former member of the U.S. Air Force and had recently re-enlisted in the Army and begun training with the Menasha Police Auxilary, WFRV reports. He had no known connection to the victims.

Fundraising for the family

Erin Stoffel suffered three gunshot wounds, a fundraising page for the family says. The family's youngest children – ages 5 and 7 – were also there at the time of the shooting, but weren't physically harmed.

In just four hours, the GoFundMe page has raised more than $10,000 for the Stoffel family.

This is one of the deadliest shootings in the Fox Cities' history, reports noted. The police department has made counseling available for the community, according to a post on Facebook.

The Fox Cities Trestle Trail, which opened in 2005 and was given a major upgrade five years later, is the longest pedestrian water bridge in Wisconsin, the Post-Crescent reports. It is used by nearly 1,000 people per day.

"The bloodshed of a mass murder will now be attached to this beautiful site," the paper lamented.

The bridge was closed Monday, but is expected to reopen later in the day, police said on Facebook.
