A man accused of fatally shooting his brother this year was taken into custody after barricading himself inside a Monument home Tuesday after deputies tried to approach him about assault, said Jacqueline Kirby, spokeswoman for the El Paso County Sheriff's Office.

Erik Mattyasovsky, 31, was arrested April 24 on suspicion of reckless manslaughter and posted $10,000 bond that day, court records show. He pleaded not guilty in June.

But about 4:30 p.m., deputies responded to a report of "a family disturbance that quickly escalated" in the 1000 block of Bowstring Road, Kirby said.

Mattyasovsky was seen running into the home and was believed to be the only one inside. Authorities said they didn't know whether he was armed.

The Monument man is suspected of assault on two people, Kirby said. Both were injured, but neither was hospitalized, she said.

Residents within a half-mile radius were asked to remain sheltered in place, and Lewis-Palmer high school and middle school were on lockout status for a little less than an hour, Kirby said.

"We want to make sure that we're protecting the community, especially when we don't know what we're dealing with - what kind of weapons may or may not be in the house and the state of mind of the individual who had barricaded himself," she said.

Mattyasovsky was apprehended shortly before 11 p.m. Tuesday, Kirby said. He was arrested on suspicion of second-degree assault with a deadly weapon, two counts of third-degree assault and three counts of harassment - striking, shoving or kicking - court records show.

He remained in El Paso County jail Wednesday evening on $50,000 bond, inmate records show.

In April, Mattyasovsky had said he and brother Brian Mattyasovsky, 35, were taking turns pointing a loaded semi-automatic handgun at each other and pulling the trigger, practicing "defensive techniques," when the gun fired and killed his brother.

He called the shooting an accident, but authorities were dubious because he did not immediately call 911.

Court records show he previously had been accused of offenses including disorderly conduct and harassment.

In November 2007, Mattyasovsky allegedly rammed his vehicle into a car driven by an off-duty officer in Colorado Springs, Gazette news partner KKTV reported at the time. He reportedly threatened the officer, then cut his neck and wrists in an apparent suicide attempt during a brief standoff.
