An on-again, off-again Wisconsin couple involved in a police standoff shut down one of Wisconsin’s busiest highways for 12 hours on Tuesday, and the woman began live-streaming on Facebook when she said her partner was holding her hostage, The Milwaukee-Journal Sentinel reported.

“He has a gun. He is going to blow my brains out,” the woman can be heard saying in the video. “Everybody, Facebook live. Record this and keep posting … I know it’s going to be gruesome.”

The Waukesha County Sheriff’s Office said in a statement they are investigating, and have not identified the couple yet, though local news outlets named the woman as Kalin Sunde, 31, and the man as Nathan Halfmann, 37.

Court records show that neither Halfmann nor Sunde have been criminally charged in the incident.

Authorities said the confrontation began when a Wisconsin Department of Natural Resources warden requested assistance to chase a stolen vehicle.

The incident then spiraled into a wild police chase, ending only when authorities used a spike strip to deflate the vehicle’s tires.

‘I’m the one that has a hostage, douche’

The couple inside “refused to comply with orders from officers to surrender” and the man demanded a negotiator, the sheriff’s office said. “The male barricaded himself in the vehicle and alleged that he was holding a female hostage.”

The Milwaukee-Journal Sentinel obtained 90 minutes of footage from the Facebook livestream, showing that at one point during negotiations with police, Halfmann demanded that authorities give them marijuana. Police appeared to give them water and cigarettes.

Halfmann also grew enraged with authorities when they refused his demands to back their vehicles away.

“Move back or Kalin gets shot,” he said. “I’m pretty sure that I’m the one that has a hostage, douche.”

After five hours of negotiations, police deployed “tactical gas” into the vehicle and Halfmann fled, still holding Sunde at gunpoint.

The confrontation ended when police fired multiple shots at Halfmann. Sunde tried to flee, and stabbed a K-9 dog named Justice.

The sheriff’s office said both Halfmann and Sunde were treated at local hospitals, with Halfmann remaining in critical condition and Sunde stable. Justice was also treated for injuries at a veterinary clinic and released Wednesday morning.
