A standoff Thursday at 1912 Banks Ave., Superior, ended with a woman jumping from a second-story window.

According to a news release from the Superior Police Department, officers responded to a report of a neighbor dispute at about 6:25 a.m., and found that the upstairs tenant of a duplex allegedly threatened the downstairs tenant with a hammer and, later, at least one knife. The suspect also allegedly bit the victim.

As the situation unfolded, "it became apparent that a more robust response was necessary to deescalate," police said. The suspect refused to speak with officers about the allegations, allegedly threatened to "blow the duplex up" and retreated back to the duplex and stopped communicating with officers.

The Emergency Response Team, including crisis negotiators, was deployed due to the uncooperativeness of the person causing the disturbance, the news release said. The public was asked to stay away from the area. A Superior police armored vehicle was at the scene. Police officers were seen in SWAT gear with guns at the door.

Officers were asking for a woman named Tracy to come outside and then threw a phone into the house. “Tracy, come grab the phone and speak to us," an officer said over a loudspeaker. According to a later news release, police attempted to negotiate a peaceful surrender for four hours.

Police entered the second floor of the duplex at approximately 10:30 a.m. There was the sound of glass breaking and tear gas was deployed. A person inside could be heard coughing and crying.

Superior police later clarified that a "volley of seven non-burning chemical irritant rounds" were deployed into the apartment.

"The round we used does not generate heat or flame," a news release from police stated. "The chemical irritant contained in the round is nonflammable and does not interact with other chemicals or with things commonly found in the environment where it is deployed."

At around 11:50 a.m., two loud bangs could be heard coming from inside the residence and tear gas was again deployed. An officer warned bystanders that they might feel the "effect." Flames were coming out of a window.

At this point, the suspect was seen jumping from a second-story window. She was then detained and taken to a Mayo ambulance that was standing by.

Two dogs were taken from inside the building after the fire started. Superior firefighters remained on the scene to put out the fire.

Workers from Superior Water, Light and Power cut utilities to the building during the incident.

The Douglas County Sheriff's Office and members of the UW Public Safety Department have been called in to take over the crime scene and the Wisconsin Department of Criminal Investigation was called to the scene to investigate the origin of the fire.

This standoff comes just a week after the Duluth Police Department responded to a domestic abuse call that turned into a standoff with the suspect for more than 16 hours. That standoff resulted in the death of K-9 Luna and the suspect.
