Lt. Todd Schulz of the Fort Atkinson Police Department tells us officers were called around 5:30 p.m. to a domestic disturbance involving a 53-year-old woman at a Fort Atkinson residence.
Lt. Schulz says around 7:00 p.m. officers went back to the home after reports the woman had guns and had retreated to another part of the home.
At this point the Jefferson County Sheriff's Tactical Unit was called in and perimeter was set up in the area between Fort Atkinson Middle School and The Hoard Historical Museum.
Lt. Schulz says a negotiator has made contact with the suspect. The standoff situation is ongoing. Both Fort Atkinson Police and the Tactical Unit remain on scene.
