SIOUX CITY, Iowa (KCAU) — UPDATE (3:20 p.m.): Officials have provided new details regarding a homicide and officer-involved shooting overnight.

In a Monday afternoon press conference, Woodbury County Sheriff Chad Sheehan said the Woodbury County Communications Center received a 911 call Sunday around 7:31 p.m. from a man saying his son was shooting at him at a residence in the 2500 block of D25, or Old Highway 141. That location is about four miles north of Hornick.

Authorities responded to the scene and set up a perimeter. In a previous release, authorities arrived at the scene and found a victim. Authorities learned that the suspect, Walter Sulsberger, 44, was still on the scene in a white pickup. At 9:10 p.m., Sheehan said he spoke with Walter Sulsberger via phone, who allegedly said that there would be no peaceful resolution and made threats to law enforcement.

The sheriff’s office requested assistance from other law enforcement. Those included the Sioux City Police Department, the Iowa State Patrol, and the Tri County CERT Team sending armored vehicles and tactical personnel and the ISP providing air support.

A negotiator tried to negotiate a peaceful surrender, but Walter Sulsberger allegedly fired multiple shots at tactical teams who were trying to move in to take the suspect into custody.
Law enforcement returned fire and hit Walter Sulsberger. Medical personnel were called to the scene but he was pronounced dead.

The shooting victim had also died. He was identified as Walter Sulsberger’s father, Todd Sulsberger, 72.

The Iowa Division of Criminal Investigation will be further investigating the shooting and homicide.

Sheehan said that body cameras were being used by law enforcement, but doesn’t know whether they will be dependent on the investigation. Whether they will be released will most likely be up to the Woodbury County Attorney’s Office
