A Kentucky man who allegedly made threats to kill his family was stopped during a traffic stop and officers discovered that the individual was wearing body armor and had multiple loaded guns in his possession, according to authorities.

On May 20, police were notified that Kenneth Gregory, 27, had “made threats to harm himself and others,” according to the Oldham County Police Department.

Officers went to his home in Louisville, but he had already left. While officers were at his home, Gregory reportedly called his father on FaceTime while wearing ballistic body armor and loaded magazines.

Gregory is also accused of sending threatening texts and left a voicemail threatening to kill his father: “I’m going to kill you. I’m going to kill your… family. I… hate you, and I’m on my way to do so,” he said in the message, according to officials.

Police were able to ping Gregory’s location and pulled him over as he was approaching his stepsister’s home in Oldham County.

According to authorities, Gregory had a 9mm pistol holstered on his hip, along with two 9mm magazines and two AK-47 magazines. Officers said they also found a loaded AK-47 and additional magazines in the front of the car.

Court documents state Gregory threatened to kill his stepsister, her husband and their two children, but a motive is unclear.

Gregory had an “active mental inquest warrant” from Jefferson County, which allows someone to be picked up by police for treatment, officials said.

He was arrested and charged with four counts of attempted murder. He is being held on a $100,000 bond and is due in court on May 31 for a preliminary hearing, authorities said.
