The mother of a 20-year-old man who was shot and killed by police on Sunday said she was speaking to him on the phone just before his death, and that she saw him on a video call after he was shot.

According to NBC News, Katie Wright said her son called her when police in Brooklyn Center pulled him over on Sunday, and that she could hear officers speaking to him in the background, telling him to exit the vehicle.

“Daunte asks, ‘For what?’,’ his mother told NBC News. “The police officer said, ‘I’ll explain to you when you get out of the car.’ He said, ‘Am I in trouble?’ He said, ‘We’ll explain all of that when you step out of the car.”

Katie and her son were disconnected, but she called back a short time after that, and Daunte’s passenger–believed to be his girlfriend–picked up the video call.

“She pointed the phone toward the driver’s seat, and my son was laying there unresponsive,” Katie Wright told the news outlet. “That was the last time that I have seen my son. That was the last time I’ve heard from my son, and I have had no explanation since then.”

Katie Potter, the officer who shot Daunte Wright, has since been arrested and charged with second-degree manslaughter.

At a news conference Monday, former Brooklyn Center Police Chief Tim Gannon said he believed Potter meant to use her taser gun but accidentally discharged her firearm. In police body cam video shown at the news conference, Potter can be heard shouting “Taser! Taser,” before shooting Daunte Wright. She later says, “Holy s*** I shot him.”

Both Gannon and Potter submitted their resignations before Potter was charged. Neither resignation has been accepted, and the city council has reportedly voted to fire Gannon.
