Robert Bell, the man accused of committing manslaughter when he killed his wife, Cider Mill School teacher Svetlana Bell, last December, has been acquitted of all charges by a judge in Danbury Superior Court, according to media reports. These charges included first-degree manslaughter and disorderly conduct.

Mr. Bell, of New Fairfield, was cleared of all charges Tuesday, Dec. 3, and was released from custody. He had spent the last year held on bail.

Ms. Bell was killed by her husband on Dec. 8, 2012, when she apparently became enraged following a domestic altercation at their New Fairfield home. At the time, police said Ms. Bell was shot four times by her husband. Mr. Bell’s lawyer later told NBC Connecticut his client regularly carried a sidearm pistol, and was a firearm training expert.

Police said they received a 911 call from Robert Bell on Dec. 8, 2012, requesting an ambulance shortly after 7 p.m., according to the Associated Press. When they arrived at the house, police found Svetlana Bell unresponsive on the kitchen floor, with apparent gunshot wounds to her chest. She was taken to Danbury Hospital, where she was pronounced dead a short time later.

Mr. Bell later said he was acting in self-defense when he shot his wife, as she was moving toward him with a knife at the time.

Police recovered a knife near the body of Ms. Bell.
