A former hero Trumbull police officer who retired last year after two domestic violence arrests regarding an affair he had with an officer he was training has been charged with using a police department computer to find a teenage girl who had accused him of sexual assault. Michael Gonzalez, 41, who made national news in 2010 when he donated a portion of his liver to the hospitalized 15-year-old daughter of a fellow officer, surrendered at state police Troop F in Westbrook Thursday morning after being told there was a warrant for his arrest. He was charged with third-degree computer crime and released after posting $75,000 bond pending arraignment in Superior Court in Bridgeport on July 11. Gonzalez had been under investigation for allegedly sexually assaulting a teenage girl who had been in the Trumbull Police Department\u2019s explorer program, but not charged. Police Chief Michael Lombardo contacted the Trumbull Times July 3 to clarify that the girl was a former member of the program. State police said the statute of limitations on the charge that would have been levied against him, fourth-degree sexual assault, had already passed. The alleged sexual assault occurred in August 2017, police said. During the investigation of the sexual assault complaint, state police said, they determined that on two occasions, March 17 and April 24, 2017, Gonzalez illegally used Trumbull Police Department\u2019s National Crime Index Computer to search for addresses and vehicles listed to the complainant of the sexual assault. Earlier this year, Gonzalez was granted entry into the Family Violence Education Program following his domestic violence arrests. He was allowed to retire from the police department with his benefits. On June 18, 2018, Gonzalez was charged with third-degree assault, second-degree threatening and disorderly conduct and Kaitlyn Arcamone, 28, also a Trumbull officer, was charged with disorderly conduct. Trumbull police contacted Stratford police to report a domestic violence incident that occurred in Stratford on March 24, 2018, involving two police officers, according to the arrest warrant affidavits. Stratford police subsequently interviewed Arcamone. Police said Arcamone, who had been on the Trumbull Police Department less than a year and was being trained by Gonzalez, told Stratford police she and Gonzalez got into an argument at his home in Stratford. Gonzalez, who was married to a police officer, told Arcamone he was going to have sexual relations with another woman, she slapped him, and a physical altercation escalated, police said. Arcamone was later fired by the Police Department. This is the second time a member of the Trumbull Police Department has been accused of sexually assaulting a teenage girl under his supervision in the department\u2019s Explorer program. In January 2015, William Ruscoe, a 20-year veteran of the Trumbull Police Department, was sentenced to 30 months in prison after pleading guilty to second-degree sexual assault. The teenage girl told police Ruscoe had driven her to his Trumbull home. When she balked at having sex with him, the affidavit states, Ruscoe plunked his service weapon down on the kitchen counter in front of her and then ordered her upstairs to his bedroom, grabbing his handcuffs on the way up the stairs. Once in the bedroom he pulled off the teen\u2019s cadet uniform and, over her many protests, sexually assaulted her, the affidavit states. The teen\u2019s family has a lawsuit pending against the town of Trumbull.
