Danville police said a man entered a home on Old Shakertown Road in Danville on Wednesday, carrying a handgun.
Police say another man inside the home, in his early 60s, was forced to the ground at gunpoint. According to investigators, Armstrong forced the victim to give him money and medications before taking off on foot.Police say they believed the suspect is familiar with the occupants of the house; his mother appears to be an acquaintance.
Hours afterward, Kentucky State Police found a vehicle they say is connected to Armstrong in Harrodsburg. Police say Armstrong voluntarily went to Danville to be interviewed, and was arrested a short time later.
