A fatal shooting in the Heights on Christmas Day may have been the result of an unwelcome visit by a previous boyfriend.

According to an affidavit filed Wednesday by the Yellowstone County Attorney's Office, David Bruce Isaacson told investigators that he shot Sabah Mallak early Tuesday morning after Mallak arrived near his residence on Yellowstone River Road.

The affidavit, filed by Chief Deputy Rod Souza, states that Isaacson said he fired at Mallak with a .357-caliber revolver when Mallak drove toward him in a vehicle.

Mallak got out the vehicle, Isaacson reportedly told Billings police detectives, and Isaacson shot him numerous times.

Isaacson, 41, is being held in the Yellowstone County jail on possible charges of deliberate homicide and tampering. He is expected to make his initial appearance in Justice Court on Thursday, Souza said.

The affidavit, which includes new details of the shooting, was filed by Souza to establish probable cause to detain Isaacson until he makes his first court appearance. Judge Larry Herman signed the document.

Neighbors reported gunshots in the area of Galway Drive and Hawthorne Lane at about 1 a.m.

When officers arrived, they found a Pontiac Grand Am crashed into a fence in a yard on Galway Drive and Mallak lying in the street in front of the house. The 34-year-old Mallak was pronounced dead at the scene, police said.

In the affidavit, Souza said an autopsy determined that Mallak had bullet wounds to the buttocks, the left upper back and the center of his chest.

The affidavit states that when officers arrived they spoke with Isaacson and his girlfriend, Daniell Calhoun, who lives about a block from the shooting scene on Yellowstone River Road.

Isaacson and Calhoun "both denied any involvement" in the shooting, the affidavit states, and said they drove to the area after hearing "pops." 

Officers "noticed inconsistencies in the information Calhoun and (Isaacson) were providing," the affidavit states, and they were taken into custody for further questioning.

Isaacson then told officers that Calhoun had been involved previously in an abusive relationship with Mallak, and she had told him that Mallak would be "driving by their house early on Christmas morning."

Calhoun and Isaacson started to argue, according to the affidavit, and Calhoun left the house to meet Mallak.

Isaacson said he then left the house with the pistol, walked down an alley and saw Mallak in a vehicle near the intersection of Linden and Galway drives. Calhoun was outside the vehicle, he said.

Isaacson "said Mallak drove west on Galway toward him," the affidavit states.

Isaacson said he shot at the vehicle, which then crashed into the fence. Mallak got out of the vehicle, Isaacson reportedly said, and he shot him numerous times.

Isaacson said he threw the gun over a railing on Yellowstone River Road toward the river bottom. The pistol was found later Tuesday morning about 30 feet down a steep embankment.

Souza said in the affidavit that five spent shell casings were found in the gun.
