• Authorities claim Long Thao shot his brother in the back after the two spent hours drinking and gambling at Oneida Casino.
• Surveillance footage reportedly captured the incident, showing the suspect standing over the victim and subsequently fleeing in a white Honda Accord.
• Law enforcement states that Thao, who was allegedly prohibited from owning firearms, was apprehended following a brief chase and is facing multiple felony charges.

An individual from Appleton, Wisconsin, has been charged with attempted first-degree intentional homicide using a dangerous weapon, after allegedly shooting his brother in the back inside the parking garage of Oneida Casino following a night of drinking that included 12 shots of tequila and two margaritas.

On Monday, Long Thao, 39, was also charged with unlawful possession of a firearm by a felon, violating a firearm injunction, endangering safety while intoxicated, and resisting an officer by failing to stop his vehicle.

The shooting incident took place early Saturday morning at the Green Bay, Wisconsin casino, as per a criminal complaint filed in Brown County Circuit Court. Police received calls around 1:53 a.m. reporting that a man had been shot by his brother on the second level of the parking garage.

The victim, identified only by initials in court documents, was located by police and casino security with a gunshot wound to the middle of his back. He received on-site treatment before being transported to a nearby hospital. Authorities have yet to provide an update on his condition.

Details regarding Thao’s alcohol consumption stem from the victim’s account shared with authorities.

Brothers’ Background

The events unfolded after a night filled with drinking and gaming, prosecutors assert. The victim indicated he arrived at the casino around 10:30 p.m. on Friday, while Thao and two women arrived in Thao’s white Honda Accord.

At approximately 1 a.m., the victim reported that Thao began discussing their “history” and attempted to provoke an argument. Thao then suggested they proceed to the parking garage, which the victim believed was for a private conversation.

Casino surveillance footage captured Thao standing over the victim while pointing the gun before escaping in the Honda, according to the prosecutors.

“Long then stood over me and aimed the firearm at my head,” the victim told the police. “The gun was within 3 feet of me. I expressed my love for him, fearing for my life. Long’s intention was to kill me. He shot me deliberately to end my life, then put away the gun and drove off.”

Pursuit by Authorities

A deputy from Brown County later observed a white Honda Accord matching the suspect vehicle traveling eastbound on State Highway 172. When ordered to stop, the vehicle failed to comply, initiating a chase.

Law enforcement carried out a high-risk stop and arrested Thao. A handgun was discovered on the passenger seat, according to the complaint.

Thao declined to undergo field sobriety tests and a preliminary breath test, according to court documents. When informed of his Miranda rights, he claimed to be too intoxicated to comprehend them, as alleged by prosecutors.

At the time of the incident, Thao was prohibited from firearm possession due to a previous felony conviction and a domestic abuse injunction, according to the complaint.

A cash bond of $750,000 was set for Thao by a Brown County court commissioner.
