Council Bluffs police said a man was arrested this week for torturing his dog. 29-year-old Marshon Johanson, a convicted felon in Nebraska who was not allowed to own a handgun, was charged with animal neglect resulting in serious injury or death, animal torture and felon in possession of a firearm. According to online court records, Johanson, of Council Bluffs, remains held in the Pottawattamie County Jail on a $7,000 cash-only bond. His preliminary hearing was set for August 18^th.

According to KETV CBPD animal control officers was called to a home near 34th and Avenue G around Aug. 7th for a man who was bitten by a dog and, in return, shot the dog. Police said they were told it may have happened weeks ago.

A court affidavit said Johanson believed it was around the Fourth of July that the dog bit him, he hit it in the chest with a pick-style axe weapon causing an injury, then got the gun and took the dog to the basement to try and shoot it to death.

CBPD said the man who answered the door of the home was uncooperative when they went to check the welfare of the dog. Witnesses told police the man was bitten two weeks before the call, and the dog was shot but alive in the home.

Officers and animal control said they got a warrant to search the home and tried to serve it on Aug. 9.

CBPD said an unrelated person and their 3-year-old child were at the home on Aug. 9, and allegedly, the 3-year-old tried to touch the dog, possibly at the site of the gunshot wound, and the dog bit the 3-year-old. Police said the owner then hanged the dog after the child was bit, and as officers showed up to serve their warrant, they found the dog hanging from rafters in the basement.

According to an affidavit, Johanson had adopted the dog around four months ago, and it had bitten him in the past. The court document said Johanson admitted to dragging the dog to the basement. Officers found the handgun, as well as the dog hanging from a rope in the basement.

The court document said Johanson told them it took 45 minutes to successfully kill the dog by hanging it. Johanson is a convicted felon in Nebraska and is not allowed to own a handgun.
