Norwich — Police, who have made two arrests in a Dec. 1, 2017, home invasion at 83 W. Town St., are asking the public to help them identify and find a third suspect.

Police described the suspect as a Hispanic male possibly nicknamed “Psycho,” who is 5 feet 8 inches tall and in his early 20s. Police said he has a stocky build and keeps his long black hair in a ponytail or bun.

Police on April 27 charged Daniel O’Brien, 54, of 87 W. Town St. with accessory to commit home invasion, accessory to first-degree robbery, accessory to third-degree larceny, conspiracy to commit home invasion, conspiracy to commit first-degree robbery and conspiracy to commit third-degree larceny in connection with the incident.

On May 21, they charged Luis Ruiz, 39, of Meriden with home invasion, second-degree assault, first-degree robbery and third-degree larceny.

Police said a bitter business partnership breakup led to the home invasion and assault, in which two men entered the home, stole $8,000 and left one victim with several fractures to the face and head.

O’Brien allegedly enlisted Ruiz and a man nicknamed “Psycho” to go to the home. Police said O’Brien used to work at Autumn Oaks Investment LLC, which manages boarding and sober homes, with one of the victims.

Anyone with information can call Detective Kevin Wilbur at (860) 886-5561, ext. 3154, or the department’s anonymous tip line, (860) 886-5561, ext. 4.
