BROOMFIELD, Colo. -- Adams Count District Attorney Don Quick said Wednesday that no criminal charges would be filed against a Broomfield cop in a fatal shooting May 24.

Just after 10:30 p.m., officers responded to a domestic dispute call at 13005 Lowell Blvd. in Broomfield.

The address is an old school house, converted into a residential home.

Howard Kepler, 58, was in a bathroom of the home with his wife, Leigh Landskroner, 58, according to Quick.

The third resident of the home, 74-year-old Florence Landskroner, had called 911 to report her son-in-law, Kepler, had been drinking and arguing with his wife and that he also may've been armed with a gun or a knife.

Quick writes that police were told Ms. Landskroner heard her daughter yell "Don't cut me!" and, at that point, she opened the door to the bathroom to see Kepler with his pants down, yelling "Get out!"

Broomfield officers Todd Dahlbach and Clint Hess both arrived at the home within two minutes, according the Quick's letter.

Attempts to talk with the suspect failed, with officers hearing Kepler accuse his wife of infidelity.

Quick also writes the officers could hear Leigh Landskroner behind the closed bathroom door say,"put it down," "don't cut me," and "this isn't gonna end well," to her husband Kepler.

One officer tried to use a battering ram to open the door and heard three or four gunshots.

Once he was able to wedge part of his body inside Hess said he watched Kepler turn toward him, with a gun in his right hand.

Quick writes the officer fired his weapon, hitting Kepler twice in the face, killing him.

Kepler had been convicted of assaulting an Adams County sheriff's deputy in another domestic violence case from 1987 involving a different wife.

However, Quick writes, Kepler had used the exact same handgun in that case as in the fatal officer involved shooting; a Walter PPK 9-millimeter, semi-automatic pistol.

Quick writes Leigh Landskroner was killed by her husband.
