A 29-year-old Casper woman accused of stabbed her host at least twice in the back faces felony assault charges in Natrona County District Court.

Shylene Arthur remains in the Natrona County jail on a $50,000 bond, charged with two counts of aggravated assault and battery stemming from an incident on the evening of Feb. 2 on North Beech Street in the city.

An arrest affidavit shows Casper police responded to a call about a knife assault to find a man trying to force Arthur out of a residence and saying, “she stabbed my daughter.”

Officers discovered a 26-year-old woman in the home’s bathroom with one slash mark and two puncture wounds to her back, the affidavit states. The woman was transported to Banner Health Wyoming Medical Center by EMS for treatment.

Black Steak Knife

The affidavit states that arriving officers saw a black steak knife on the lawn outside the residence.

An interview with the victim revealed that she had known Arthur for a month, and on Feb. 1 had invited her to stay at her place because she was highly intoxicated, the affidavit states. The victim was out of the residence for much of Feb. 2 and returned to find Arthur sitting on the victim’s bed. Arthur allegedly yelled at the victim to “get off your belly.”

When the victim left the room to show a relative a dog, Arthur allegedly pursued her with scissors. Another relative was able to stop Arthur and calm her down, the affidavit states. The victim then cleaned up items, went outside and returned with Arthur allegedly “screaming nonsense at her.”

The affidavit states that Arthur then began screaming at the victim that “she needed to die.”

When the victim tried to run to the bathroom, Arthur allegedly started hitting her and then stabbed her, the affidavit states.

‘Rolled Into Ball’

The victim told police she “rolled into a ball” on the ground outside the bathroom, the affidavit states. Another person in the residence then grabbed the victim, pulled her inside a bathroom and called 911 while holding pressure to her wounds.

During police questioning of the victim’s father, the affidavit states he related that Arthur also held a knife toward him in a threatening manner and that he went to his room and “retrieved a sword.” Then he began trying to push Arthur out of the residence, the affidavit states.

During an interview with Arthur, she told police she was using methamphetamine with members of the household that day, the affidavit states.

“Arthur could not recall the specifics of what (the victim) told her that upset her. Arthur stated she used a long black knife, and initially admitted to stabbing (the victim) in the chest,” the affidavit states. “Arthur clarifed that she believed she actually stabbed (the victim) a couple of times in the right shoulder and the not the chest.”

In addition to a black-handled serrated steak knife outside the main entrance to the residence, which was collected for evidence, officers observed a blood stain on the carpet in a hallway between the bedroom and bathroom where the alleged knife assault took place, the affidavit states.

Both aggravated assault and battery charges that Arthur faces carry a penalty of up to 10 years in prison and a $10,000 fine.
