The defendant in an armed home invasion that occurred last February in West Dennis was found guilty by a Barnstable Superior Court jury this week. According to a release from Cape & Islands District Attorney Michael O'Keefe's Office, 30-year-old Robert W. Shanahan was sentenced in connection with a violent home invasion on Susan Way that occurred on February 24, 2013.
According to court documents, Shanahan reportedly knocked on the door of a West Dennis home around 7:30 p.m. and attacked the 56-year-old male resident who answered the door with a hammer. Shanahan reportedly forced his way into the home and struck the man several times on the head with the hammer.
During a struggle, a large kitchen knife fell out of Shanahan's jacket, according to the DA's release. The male resident was able to get Shanahan back outside and following a struggle, Shanahan fled the scene. The 49-year-old woman in the home at the time of the attack was uninjured and called 911, police said at the time.
The residents were able to identify Shanahan and he was arrested the following day by Dennis police.
The case. which was tried by ADA Nicole Manoog, lasted five days and following two and a half hours of deliberation, the jury returned a guilty finding for home invasion, armed assault in a dwelling and assault and battery with a dangerous weapon.
Shanahan was sentenced to state prison for 20 years to 20 years and one day for the home invasion, 10 years to 10 years and one day for the armed assault in a dwelling and 10 years probation for assault and battery with a dangerous weapon. The two prison terms are concurrent, according to the DA, and probation will begin following Shanahan's release.
The case was investigated by Dennis police and the Barnstable County Sheriff's Office Bureau of Criminal Investigations.
