A man having an affair with the wife of his brother who was deployed overseas at the time murdered him after being confronted about it, cops say.

Police in Iowa have arrested Kyle Andrew Coolack, 39, after two years on the lam.

Police in Houston, Texas, say he killed his younger brother in 2022. A resident of Pomeroy, a tiny town in the northeast part of the Hawkeye State some 1,000 miles away from the murder scene, called the Calhoun County Sheriff’s Office around 7:14 a.m. Sunday and said Coolack admitted to people in the home that he killed his own brother. They asked him to leave and he began walking south toward Fort Dodge.

A deputy found the suspect walking along Highway 4 and took him into custody. At first, Coolack allegedly gave the deputy a fake name but eventually admitted to his true identity. Cops confirmed he had a warrant for his arrest for the March 11, 2022, murder of his 35-year-old brother Brad Coolack.

According to a probable cause arrest affidavit, a man who identified himself as “Coolack” called 911 to say another man “was shot in the leg” and deceased. The caller, using the victim’s phone, breathed heavily and said “stay with me, bro.” He said the victim wasn’t breathing and had no pulse. Dispatchers asked the man, later identified as Kyle Coolack, how the shooting occurred and he allegedly responded that he “doesn’t know what f—— happened” and claimed he had just arrived home and found the victim shot. The caller hung up and wouldn’t answer any subsequent calls, according to cops.

Houston officers found the victim suffering from several gunshot wounds inside the bedroom of an apartment. Paramedics declared him dead. Detectives noted it appeared someone had busted through the bedroom door. They found three shell casings on the ground. An autopsy determined Brad Coolack, who by then was divorced from his wife, suffered a gunshot to the back at close range, the affidavit said.

Cops interviewed a neighbor who said she heard two men arguing just before the shooting. One allegedly said to the other: “You slept with my wife!” Gunshots quickly followed. Detectives went to the victim’s ex-wife, who confirmed she had an “extramarital affair” with her brother-in-law Kyle Coolack while her husband was deployed overseas, according to the affidavit.
