South Jordan police and a SWAT team respond Sunday, July 27, 2014, to a barricaded person at the San Marino Apartments at 776 W. Grande Rose Way.

SOUTH JORDAN — A four-hour standoff with a SWAT team ended peacefully on Sunday after a man believed to be armed was taken into police custody.

South Jordan police spokesman Sam Winkler said officers were notified shortly before 1 p.m. that Kenneth John Perna-Rutsky, 34, had brandished a handgun during a dispute with his fiance at the San Marino Apartments near 700 West and 9800 South.

The woman had fled and contacted police after Perna-Rutsky allegedly put the gun to her head and threatened to shoot her. He then pointed the gun at himself and attempted suicide, but the weapon failed to fire, according to Winkler.

When officers responded, their attempts to contact Perna-Rutzky were unsuccessful.

"He wouldn’t answer his phone or the door or anything else," Winkler said.

Police evacuated approximately 40 neighboring apartment units and a SWAT team was called to the scene. The SWAT team entered the Perna-Rutsky's apartment at 4:45 p.m., at which point he surrendered peacefully and was transported to a hospital for evaluation, Winkler said.

He was later booked into the Salt Lake County Jail for investigation of aggravated assault.
