The Louisville Metro Police Department said its officers and the U.S. Marshals Service attempted to serve the warrant just before 3 p.m.
“As they knocked and announced their presence a single gunshot was heard from within the residence,” the department said.
No officer or marshals discharged their weapons, it said. The woman was found dead inside the home from a single, self-inflicted gunshot wound, police said.
There were people inside the home, but it was not clear how many.
The department initially said the warrant was for a homicide but made the correction in a news conference after the incident. The assault warrant was related to a shooting that occurred in August involving a Lyft driver, a police spokesperson said during a Friday evening news conference.
The identity of the woman was not released. Despite police statements, some on social media claimed a Black woman was fatally shot by police, which authorities have denied.
“Unfortunately sometimes misinformation gets out there and that’s exactly where we’re here tonight,” the police spokesperson said.
