State and local authorities are investigating the fatal officer-involved shooting in Gastonia on Friday night that killed a man with a history of assaulting police.

The slain man, identified as 50-year-old Kenneth Glaze of Gastonia, had a lengthy criminal record that spanned three decades and included four convictions for assaulting officers.

On Friday night, police received a report of a domestic violence incident at a home on East Ninth Avenue, where Glaze lived with his sister.

Gastonia police said Glaze had choked his younger sister and slapped her boyfriend. Then, he assaulted them again using hedge shears, police said. The victims left the home and called police.

About 9 p.m., Gastonia police officers Michael Watts and Travis Kistler went to the home. When they arrived, the officers had a confrontation with Glaze in the backyard, police said.

“During a struggle for one of the officers’ handguns, shots were fired which fatally wounded Mr. Glaze,” police said in a statement.

It’s unclear who fired the fatal shot.

Glaze’s criminal record dates to 1978, when he was charged with shoplifting at age 16, records show. Over the course of the 1980s, he became a felon with convictions for safecracking, breaking and entering and larceny.

Between 1989 and 1996, he was convicted three times of assaulting an officer. In 1991, he escaped from a North Carolina prison, records show.

Then, he was convicted of assault with a deadly weapon on an officer in connection with a 1998 incident in which Glaze was accused of dragging a Gastonia officer who’d tried to stop him in a stolen truck.

Police told the Observer at the time that the officer had approached Glaze and reached inside the truck to shift it into park.

That’s when Glaze drove away, dragging the officer about 40 feet. The officer fired at Glaze, striking him in the shoulder. Glaze was arrested at the hospital.

Glaze’s other convictions included driving while impaired and assault on a female.

In 1999, a judge ordered Glaze to complete a substance abuse program for evaluation and treatment.

He’d most recently been released from a state prison in April after serving about seven months for assault with a deadly weapon and injury to property, according to the N.C. Department of Public Safety.

Glaze’s relatives told Observer news partner WCNC-TV that Glaze had said he never wanted to go back to prison.

“He said they’d have to kill him,” one of Glaze’s son said.

The State Bureau of Investigation and the Gastonia Police Department’s Office of Professional Standards are investigating Friday’s shooting.

The officers involved, both of whom are assigned to the department’s patrol division, were placed on paid administrative leave, which is standard procedure in officer-involved shootings.

Officer Watts, 34, joined the department in 1999. Kistler, 24, was hired in 2009.
