A former Loveland teacher who once sued Thompson School District over student abuse claims now faces felony charges for allegedly trying to kill her ex-husband.

Carrie Giesler, 48, was arrested on suspicion of misdemeanor assault, domestic violence, and second-degree burglary after the disturbance that sounds like something of a Lifetime movie.

Giesler reportedly showed up at her ex-husband's home in Fort Collins before 7 a.m. on July 5 disguised in a wig and sunglasses to ask for directions, the Coloradoan reports. Her ex, Dan Giesler, quickly recognized Carrie through her disguise - at which point she pulled out a stun gun. As Dan tried to disarm her, the stun gun went off and shocked his hand.

Dan Giesler was able to run to a neighbor's home and call police, while Carrie Giesler remained in her ex's home for about 5 minutes before fleeing on foot.

Upon arrival, officers found a wig, sunglasses, and green gardening gloves in Dan Giesler's home, as well as blood in the kitchen, entryway, driveway, and basement.

Investigators learned later on that Carrie Giesler showed up at the Weld County courthouse for the custody hearing which she and Dan Giesler were set to go to that same day. She was detained until officers could speak with her to get her side of the story.

According to police, Carrie Giesler says she doesn't remember what she did while she was in the house following the incident, however, she does remember her nose bleeding and the stun gun going off. She denied wearing the disguise and says she showed up the home to discuss the custody arrangement before going to court. (Dan Giesler filed for divorce in 2013.)

As time went on, and more evidence came up, police say "it became clear that there were more charges that were appropriate."

The "more appropriate" charges? Attempted first-degree murder after deliberation - a class 2 felony. She was taken into custody on Thursday after that charge was formally filed, and the judge set her bond at $10,000. Carrie Giesler posted the bond later that day.

Giesler is due back in court September 15.

So what's with this whole Carrie Giesler vs. Thompson School District debacle?

Back in February this year, Giesler decided to sue the district for allegedly failing to protect her from a violent student and not allowing her to document incidents or notify police.

Giesler was hired to teach a 13-year-old boy with autism for the 2014-2015 school year, says KDVR-TV. She says he physically attacked her for a 6-month period beginning October 2014.

"Walked up and open face, open handed slapped me, punched me in the ribs, kicked me in the back, spitting in my face," Giesler told the station, adding he threatened to kill her and drew pictures of the weapons he would use.

"The entire time with him going, 'Are you scared of me? Are you scared of me? You should be. I'm going to kill you, bitch," said Giesler.

Instead of reprimanding the student, Giesler's superiors took action against her, she claimed.

At the time, Thompson School District would not comment on the case.
