Army Veteran Tied Service Dog to Tree, Shot It 5 Times on Camera: Cops

An Army veteran and her soldier boyfriend have been arrested for allegedly tying her service dog to a tree and shooting it five times at close range while laughing, authorities said.

Marinna Rollins, 23, and Jarren Heng, 26, were charged with felony counts of animal cruelty and conspiracy in Fayetteville, N.C. They are being held in lieu of $25,000 bail.

The pair took videos of themselves shooting the dog execution-style with an assault rifle, authorities said. They can be heard chuckling as the dog twitches, according to the Cumberland County Sheriff’s Office.

The footage circulated on Facebook, authorities said. After Rollins shot her emotional support dog five times, Heng fired another five rounds into the dog's corpse.

“They can be heard on the tape laughing and giggling as the dog was being killed,” Cumberland County District Attorney Clark Reaves said during a Tuesday court appearance, The Fayetteville Observer reported.

The dog, named Cam, had been adopted last year by Rollins’ husband, also a soldier. When he deployed to South Korea, he left the dog with his estranged wife.

Rollins, who has been diagnosed with PTSD, later had the pit bull mix certified as a therapy dog, the paper reported.

Heng is stationed at Fort Bragg. Rollins retired earlier this year for medical reasons, officials said.

The video also shows Rollins covering the dog with a sheet and dropping it into a shallow grave in a wooded area.

Before last week’s shooting, Rollins posted a note on her Facebook page saying she “was sad that her dog had to go to a happier place,” authorities said.

Animal control officials went to Rollins' home last week after viewing the video on Facebook. The department then called in sheriff's deputies.
