The 20-year-old Brockton native accused of executing Weymouth police Officer Michael Chesna with Chesna's service weapon and then killing an innocent woman in the sanctity of her home yesterday had battled with department members and used a rock as a weapon before, according to court documents. 
 
 The 6-foot, 3-inch Emanuel A. Lopes, 20, has been free on $500 bail since November. Lopes was arrested in Weymouth Oct. 3 on charges of dealing cocaine at a beach party for minors and resisting arrest. He was due to return to Quincy District Court July 30 for a discovery hearing. 
 
 Lopes was listed in court papers as homeless at the time. Police noted Lopes' size in their report, adding, "We have fought with him before." Lopes attempted to evade arrest for the drug offenses by running, police said. 
 
 After posting bail, Lopes entered the High Point addiction treatment center in Plymouth on Nov. 25 for what court papers state were "clinical stabilization services." The papers do not disclose when he left. 
 
 The conditions of Lopes' release included remaining drug- and alcohol-free, but court records indicate he failed to appear for a random drug screening on Feb. 7. 
 
 Following a pretrial probation violation hearing on April 25, Lopes was permitted to remain free on the same conditions. 
 
 Lopes had also been arrested by Weymouth police Sept. 4 for allegedly throwing a rock through the bedroom window of a home where he'd been asked to leave earlier. 
 
 Lopes was charged with property damage and released on pretrial probation. 
 
 He is accused of picking up a large rock yesterday to disable Chesna, who was pursuing him on foot following a crash, and then murdering the 42-year-old father of two with his department-issued gun. 
 
 Lopes remains hospitalized this morning with a gunshot wound to his leg he sustained when he allegedly exchanged gunfire with responding officers at Torrey Street and Burton Terrace. 
 
 The woman killed during the incident was identified earlier today as Vera Adams, 77. 
 
 Prior to entering High Point last year, he had also sought treatment at the Massachusetts Alcohol and Substance Abuse Center in Bridgewater, court records state. 
 
 Lopes, who has not yet been arraigned. is charged with two counts of first-degree murder, possessing a firearm without a license, destruction of property, negligent operation of a motor vehicle and leaving the scene of an accident. 
 
 At the time of yesterday's events he was the subject of an active restraining order taken out by a woman last year with the same name as his own mother. 
 
 Partially redacted court papers do not specify their relationship; however, the woman testified she had Lopes' name taken off a prior lease at a home they shared with her daughter because she feared him, but that he kept showing up at new apartment. 
 
 The woman, whose abuse prevention order was issued Oct. 3, 2017, and is set to expire Sept. 28, testified, "I told him several times he couldn't stay there or visit because of his mental health/drug issues. 
 
 "Emanuel has severe mental health issues and I am afraid of what he is capable of," she wrote in an affidavit, explaining it's why she tried to move away from him. ||||| WEYMOUTH (CBS/AP) — A man accused of fatally shooting a Weymouth police officer with the officer’s own gun and an innocent bystander could be arraigned Tuesday on murder charges. 
 
 Emanuel Lopes, 20, will either be arraigned in his hospital bed or in court for the deaths of Weymouth officer Michael Chesna, a six-year veteran of the force, and 77-year-old Vera Adams, who was shot after the suspect spotted her through a sliding glass door. 
 
 He was not “medically available” to be arraigned on Monday, as previously suggested, said the Norfolk District Attorney’s Office. 
 
 Police officers and others lined a procession route Monday afternoon as Chesna’s body was taken from the medical examiner’s office in Boston to a funeral home in Weymouth. 
 
 On the sixth anniversary of Chesna becoming a police officer, he was posthumously promoted to sergeant. Hundreds attended a vigil for Chesna and Adams at Weymouth High School Monday night. His mother thanked the community for its support, saying, “Michael would be so proud.” 
 
 Weymouth police were responding to a report of a person driving erratically Sunday morning when they discovered a crashed BMW, said Norfolk District Attorney Michael Morrissey. 
 
 Chesna was trying to locate the driver of the vehicle, Morrissey said, when he spotted Lopes allegedly vandalizing a home. That’s when Lopes hit Chesna in the head with a rock. Chesna fell to the ground, and Lopes took the officer’s gun and repeatedly shot him in the head and chest, Morrissey said. 
 
 Another officer who had arrived at the scene shot Lopes in the leg. Lopes then ran off and shot Adams after he spotted her through her glass door. Police initially reported Adams was struck by crossfire, but Monday night, the Norfolk DA’s office said Lopes intentionally shot her. 
 
 Weymouth Police Chief Richard Grimes described Chesna as a 42-year-old Iraq and Afghanistan war veteran who leaves behind a wife and two young children, ages 4 and 9. Chesna was from Weymouth and graduated in 1994 from Weymouth High School. Monday was the sixth anniversary of the day he was hired to join the Weymouth force. Grimes said he had spoken to Chesna’s mother and she told him that her son joined the military “to open the doors to get in this job.” 
 
 The department set up a fund for Chesna’s family on Monday, after receiving reports of possible scam phone calls collecting money for the family. 
 
 Lopes was out of jail on pre-trial probation on a drug charge, according to WBZ’s I-Team. Weymouth Police said he was selling cocaine to a minor and resisted arrest when he was charged in 2017. A judge released Lopes on the condition that he submit to random drug testing. He was due back in court on July 30. 
 
 Last year, Lopes’ mother took out a restraining order against him, citing severe mental health issues. 
 
 The I-Team has learned that Lopes is Facebook friends with the daughter of the woman who owns the BMW Lopes crashed on Sunday. The district attorney’s office did not say that the car was stolen. Sources say Lopes uses a different name on Facebook and told officers at the time of his October arrest that he was homeless.

– 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.
