Mentally Ill or Deliberate Killer? Trial Starts for Man Charged With Killing Massachusetts Officer

DEDHAM, Mass. (AP) The prosecutor in the murder trial of a man charged with killing a Massachusetts police officer and an innocent bystander nearly five years ago told jurors in opening statements on Thursday that the suspect acted with deliberation when he used the officer's own gun to shoot him multiple times.

The defense, however, described a defendant who has spent years struggling with mental illness made worse by frequent marijuana use, who wasn't taking his medications, and who in the days before the killings was having a dispute with his longtime on-and-off girlfriend.

Emanuel Lopes, 25, faces 11 charges, including two counts of murder, in connection with the killings of Weymouth police Sgt. Michael Chesna, 42, a veteran and married father of two, and bystander Vera Adams, a 77-year-old widow, on July 15, 2018. He has pleaded not guilty.
