An Army vet who was charged with tying her PTSD therapy dog to a tree and shooting him five times as she laughed has been found dead of a possible suicide, police said.

Marinna Rollins, 23, who had been stationed at Fort Bragg, and Jarren Heng, 25, an Army special ops soldier, each faced a felony charge of cruelty to animals after the sickening crime in Fayetteville, NC, was caught on video.

Rollins was found dead about 3 a.m. Sunday in her apartment on Netherfiled Place and her death is being investigated as a suicide, Fayetteville police told WNCN.

Fayetteville police Lt. Todd Joyce declined to disclose what evidence detectives found, CBS News reported.

Cumberland County District Attorney Clark Reaves told the Fayetteville Observer that Rollins and Heng shot several videos of the cruel act and could be heard laughing as the dog was slaughtered.

Rollins was out on bail of $25,000 when she died. Heng remains out on bail in the same amount.

Her estranged husband, Fort Bragg soldier Matt Dyer, adopted the dog, whom he called Huey, from the Cumberland County Animal Shelter. He let Rollins keep the pup when he was deployed to South Korea for a year.

Dyer said that, although he and Rollins were separated, she agreed to care for Huey during his time away.

He told CBS North Carolina that during his deployment, Rollins got Huey certified as an emotional-support dog. She then changed the dog’s name to Cambouis.

“I felt like her having to take care of Huey would be good for her and would be good for Huey,” Dyer told WNCN.

A close friend of Rollins uploaded footage of the shooting to Facebook, hoping it would get attention leading to punishment.

“It’s been real, Cammy, I love you. You’re my puppy. You’re a good puppy,” a woman is heard saying in the video.

In the last clip, the woman goes over to her now-dead dog, picks him up, pushes him over, says, “I love you, you’re a good dog” and then covers him with a sheet.

Friends and family said Rollins suffered from post-traumatic stress disorder after an incident that occurred while she served in South Korea, the Observer reported.

She was medically retired from the Army in January due to her PTSD and other mental health issues, according to arrest documents.

Heng is next scheduled to appear in court May 16.
