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.
