A police officer near Boston was killed with his own service weapon Sunday morning, CBS Boston reports. Weymouth Police Department officers were responding to a call about an erratic driver around 7:30am and found a crashed BMW. While searching for the driver, officer Michael Chesna, a married Iraq and Afghanistan veteran with two kids ages 4 and 9, found Emanuel Lopes, 20, allegedly vandalizing a home. Chesna drew his gun and ordered Lopes to stop, but, police say, Lopes threw a rock at Chesna, hitting him in the head and knocking him to the ground. Lopes then allegedly took Chesna's gun and shot him multiple times in the head and chest. Officers fired on Lopes and gave chase as he allegedly continued to shoot, CNN reports. One of Lopes' alleged shots killed Vera Adams, 77, who was sitting inside her home nearby.
Lopes had been arrested in September for allegedly throwing a rock through the bedroom window of a home he'd been asked to leave; he was charged with property damage and released on pre-trial probation. He was arrested again in October on charges of dealing cocaine and resisting arrest, the Boston Herald reports; he was freed on bail in November and was due in court July 30 for those charges. He had entered an addiction treatment center sometime after posting bail in November, court papers show, but it's not clear when he left. As a condition of his probation he was required to remain free of drugs and alcohol, but he allegedly failed to appear for a random drug screening in February; at a pre-trial probation violation hearing in April, he was allowed to remain free with the same conditions. He is currently hospitalized for a non-life-threatening gunshot wound to his leg.
