A mentally ill woman threatened suicide. Then police killed her.

A SWAT team broke into a Kristen Ambury’s home to try and save her after she threatened to kill herself Aug. 25—but it ended in tragedy, according to the Sun Sentinel.

Ambury was reportedly armed as she barricaded herself for more than three hours in her apartment in Sunrise, Florida, according to the Sun Sentinel.

Relatives told Local 10 she seemed to be under the influence of alcohol and struggled with mental illness.

Ambury, 28, had attended U.S. Army boot camp, but never graduated, according to WPLG Local 10. She told relatives, friends and neighbors that she did graduate and seems to have embellished her involvement with the Army, a reporter for Local10 told McClatchy by email.

Officers from the Sunrise Police Department attempted to negotiate with Ambury before they entered her home. When negotiations failed, a Sunrise PD SWAT team was called in, a Broward Sheriff's Office spokeswoman told Local 10. Neighbors said they heard five to six shots fired. She was home alone.

Local 10 reported that she was pronounced dead at the scene, and that officers told the station that they sent the most well-trained officers they could to help Ambury.

Broward Sheriff's Office is investigating the shooting.

So far this year, 648 people have been shot and killed by police, according to The Washington Post. Out of those people, 152 people were mentally ill.

According to the U.S. Department of Veterans Affairs, about 11-20 percent of veterans have PTSD in a given year from Operations Iraqi Freedom and Enduring Freedom.

This story has been updated to say the Sunrise Police Department responded to the incident and that Ambury may have embellished her involvement with the U.S. Army.
