According to a police report, Rollins and Heng took the gray-and-white male pit bull named Camboui to an unknown wooded area on April 16 or 17. When they got there, she tied the dog to a tree and then shot her pet in the head with a rifle.
She shot him five times, according to the report. Heng was heard on the video asking Rollins to let him shoot the dog, too.
He then shot the dog five times in rapid succession, an act also seen on the video. According to the report and the video, Rollins then dragged the dog to a shallow grave and spoke to him.
In the video, which was obtained by ABC11, a female voice can be heard talking to the dog shortly before she lifted his limp body and placed him in the grave, then draped a white sheet over him.
"It's been real ... I love you, you're my puppy, you're a good puppy, but...," the female voice says to the pup in the video.
ABC11 is not showing the video because of the graphic nature of the content.
"Kind of put him a little deeper in there," a man's voice can be heard saying as Rollins pushes the dog into the shallow grave.
Police said that before shooting her dog, Rollins posted a photo of her dog on her Facebook page along with text that she "was sad that her dog had to go to a happier place."
Police also said she sent text messages confessing to shooting her dog.
