Three people involved in an armed home invasion/robbery in Ledyard on July 20, 2017, have been sentenced in New London Superior Court.

Kylie Pierson, 37, of Norwich was sentenced May 16 to 10 years in prison, suspended after three years served, followed by three years' probation. He had pleaded guilty in March to second-degree robbery.

Mitchell Ellerbe, 33, of Hartford, also known as "Krook," was sentenced in December 2018 to eight years in prison followed by five years of special parole. He had pleaded guilty to first-degree robbery with a firearm.

According to court documents, Kristal Lis, 29, of Mystic, who had regularly provided paid sexual services to a 72-year-old man who lived on Smith Pond Way, set up and participated in the robbery of her customer.

Ellerbe, Lis and another man forced their way into the home at 10:40 p.m., and Pierson stayed in the car, according to the state. The two men had their faces covered and were wearing gloves.

Lis pleaded guilty to second-degree robbery and was sentenced in March to 10 years in prison, suspended after five years served, followed by three years of probation.

The victim, who is not identified in arrest warrant affidavits prepared by Ledyard police Detective Christopher Cadro, told police he was watching a movie with his girlfriend when two black men came in, one holding a revolver and wearing a scarf on his face, and robbed him of money, 15 firearms that have not been recovered, laptops and other items. They also stole the man's pickup truck and left it on Chapman Lane, according to court documents.

The male victim said that one of the robbers pointed a gun at him and said, "If you look at me, I will shoot you." He said the other robber carried a duffel bag that the robbers loaded with guns, ammunition and other items. One of the men told the other, "Go get the girl, we have (expletive) to load up," according to the affidavit.

The girlfriend, also unidentified in the court document, told police a man pointed a gun at her and made her lie down on the ground, and that there was a female in the home along with the two males. She said they stole her purse.

The male victim later admitted to police that he had been "hooking up" sexually with Lis once a month for the past five years.

Ledyard officer Jason Pudvah used video from a nearby Henny Penny, where the suspects had stopped to buy gas and cigarettes, to identify them. During the investigation, the police seized Pierson's car and the suspects' cellphones and conducted DNA testing on clothing that was found near the scene.
