Police say Gulley shot and killed Mauricio after he and Leandro pulled up next to his parked vehicle in a pickup, and Mauricio got out of the passenger's side brandishing a large pipe wrench in a threatening manner.

Police say Leandro then drove to his nearby house to get a gun, returned to the scene, and shot at Gulley, who returned fire.

Both were taken to the hospital with non-life-threatening injuries.

Leandro was arrested Friday and charged with three counts of aggravated assault and battery with a deadly weapon and attempted first-degree murder.

He made his initial appearance in Circuit Court on Tuesday morning and is scheduled to be back in court next Wednesday, Feb. 28, at 1:30 p.m. for his preliminary hearing.

As of 3:15 p.m. Tuesday, no charges had been filed against Gulley.

The Deadly Shooting

According to police spokeswoman Alex Farkas, officers were called to a report of a shooting in the 3300 block of Dunn Avenue around 2 p.m. on Thursday, Feb. 15,  and determined that three men had been shot.

Farkas says two shooters, 18-year-old Leandro Dominguez and 24-year-old James Gulley, both from Cheyenne, were taken to the hospital with non-life-threatening injuries, and Dominguez's brother, 22-year-old Mauricio Dominguez Jr., also from Cheyenne, was pronounced dead at the scene.

She says detectives learned that Gulley and 31-year-old Casper resident Danielle Krix were parked in a white passenger vehicle on 2nd Avenue, west of Dunn Avenue, when the Dominguez brothers pulled up next to them in a red pickup.

"Mauricio Dominguez got out of the passenger side of the truck brandishing a large pipe wrench in a threatening manner," Farkas said in a news release.

"Gulley simultaneously exited the driver’s side of his vehicle, pulled out a firearm, and shot at Mauricio Dominguez multiple times, killing him," she added. "Gulley then called 9-1-1 to report the incident."

Farkas says Leandro Dominguez drove to his nearby house to get a gun, then returned to the scene, pointed the gun toward Gulley and Krix, and shot at Gulley, who returned fire.

"Gulley’s brother, Darnell Gulley, 18, from Cheyenne, heard the altercation from his residence and walked toward the scene," said Farkas. "He was nearly struck by the bullets while approaching and fled from the gunfire."

Farkas says there were several bystanders in the area, but no other injuries were reported.
