The Huntsville Police Department is looking for a man it says assaulted his girlfriend and her dog.

Police say Jonathan Tyler Knight, 29, has a warrant for felony domestic violence (strangulation) and another for cruelty to an animal.

Lt. Michael Johnson, police spokesman, said Knight was kicked out of Panoply on Saturday for being belligerent. The department says he then assaulted his girlfriend and her dog at another location.

"This is a very unique type of assault where someone's breathing is cut off. There has to be some very pertinent evidence that visible on the victim. It allows us to charge him with a felony," said Lt. Johnson.

The dog was treated for broken ribs and internal bleeding. It later died from the injuries.

"Anybody willing to go as far as to kill an innocent K9, what else are they willing to do?" said Lt. Johnson.

WAAY 31 talked to Knight's ex-wife over the phone. She said he beat the dog in front of the children they share, and they were pleading for him to stop.

Court records shows Knight was arrested for domestic violence in 2015. The victim took out a protection order against him, saying he beat and tried to strangle her. The charges were eventually dropped.

Anyone who knows how police can locate Knight is asked to call Huntsville Police at 256-722-7100 or Criminal Investigative Division at 256-427-7270. The department said anyone who comes forward with where he might be can remain anonymous.
