A lawsuit has been filed by a woman against the Danbury Police Officer who shot her and killed her son during a confrontation last year. Linda Arbitelle claims Alex Relyea used excessive force. The lawsuit does not seek specific monetary damages. 45-year-old Paul Arbitelle was fatally shot after investigators say he came at Relyea with a knife. His 74-year old mother was seriously wounded. The state's Attorney ruled Relyea's use of such force was both reasonable and justified under the circumstances. The suit says the conduct was not objectively reasonable, shocks the conscience of the community and offends hardened sensibilities.
