A Williston man, who had served time for killing a man 20 years before in Bradford County, brought a handgun to work at Well Bilt Industries on Wednesday and threatened to kill any co-worker who said anything, according to the Williston Police Department.

Richard Williams, 50, was arrested after Well Bilt's business owner, Carol Bilt, called the police.

When authorities responded, officers interviewed all parties and recovered the gun, which Williams had hidden in a piece of pipe.

Police obtained a search warrant for his vehicle and discovered ammunition for the gun, which is illegal for a felon to possess. Also, according to police, he had been physically and emotionally abusing his girlfriend for the past year, which went unreported until his arrest.

Williams had recently received a notice of repossession for his vehicle and was behind in other payments despite his $22 an hour job as a manufacturing superintendent.
