Robert W. Shanahan Disposition

Cape and Islands District Attorney Michael O’Keefe announced today that a Barnstable County Jury in the Superior Court returned a guilty verdict on Tuesday, February 10, 2015, in the case of Robert W. Shanahan. The trial began on February 4th and the case went to the jurors on February 9th.  The jury deliberated for 2 ½ hours before finding the defendant guilty of Home Invasion, Armed Assault in a Dwelling and Assault and Battery with a Dangerous Weapon. 

On the evening of February 24, 2013, the defendant, Robert Shanahan, knocked on the door of a home in West Dennis in which a man and woman resided. When the male resident of the home answered the door, the defendant immediately attacked him with a hammer, forcing his way inside the home, and striking the male resident on the head with the hammer numerous times. During the ensuing struggle, a large bladed kitchen knife fell out of the defendant’s jacket onto the floor. The male resident forced the defendant outside onto the front lawn, where the struggle continued.  Eventually, the male resident was able to wrestle the hammer away from the defendant, who then fled the scene.  The residents of the home were able to identify the defendant, who was arrested the next day by Sgt. Mark Conant of the Dennis Police Department.

Defendant Shanahan was sentenced to 20 years to 20 years and one day in State Prison on the Home Invasion, 10 years to 10 years and one day in State Prison on the Armed Assault in a Dwelling, to run concurrently with the sentence on the Home Invasion, and sentenced to 10 years probation on the Assault and Battery Dangerous Weapon. Probation is to begin after the defendant has served his prison sentence.

Investigation was led by Det. Thomas Downs and Sgt. Mark Conant of the Dennis Police Department and Barnstable County Sheriff’s Bureau of Criminal Investigations. The case was prosecuted by Assistant District Attorney Nicole Manoog.
