A Wisconsin woman has died after a police officer accidentally ran over her in a squad car on Thursday, authorities said.

The woman from Milwaukee, 42, had been lying in the roadway when police in Greenfield, just outside Milwaukee, responded to a call for a welfare check for a female after 6 p.m., according to a news release from the police department. The responding officer was unaware she was in the road and accidentally drove over her, police said.

The officer called for an ambulance and the Greenfield Fire Department also responded to the scene. 

The woman was transported to Froedtert Hospital for what police said at the time were believed to be non-life-threatening injuries. The woman later died at the hospital.

The officer involved in the situation has been placed on administrative leave, according to Greenfield police.

The Milwaukee Area Investigative Team will be investigating the incident and the Wisconsin State Patrol will be reconstructing the accident scene, officials said. An independent review of the incident will also be conducted by the Milwaukee County District Attorney’s Office.
