Investigators with the Cumberland County Sheriff’s Office are seeking the public’s help in identifying a man who beat a Casco resident inside his home on Sunday night.

According to Lt. Donald Foss, deputies responded to a 911 call at a residence on Timbuktu Drive off Tenney Hill Road in Casco at about 6:10 p.m. The caller reported that a man entered the home and assaulted a male resident.

During the investigation, deputies learned that an unknown male had arrived at the home and knocked on the door. When the male resident opened the door, the suspect proceeded to violently beat the male resident with his fist, rendering him nearly unconscious. The victim’s girlfriend was present at the time and was not injured, Foss said.

The 31-year-old male victim was transported to Maine Medical Center by Casco Fire/EMS. He remains hospitalized with significant facial and shoulder injuries. There were no known weapons used in the attack, Foss said.

The suspect was not known to the occupants. The suspect is described as a caucasian male, 25-35 years old, 6-feet-2 to 6-feet-4, with short brown hair and a neatly trimmed beard and moustache. The suspect was wearing a long, black trench coat at the time of the assault.

Anyone with information regarding the incident is urged to contact Sheriff’s Office Detectives division at 774-1444, ext. 2173.
