Teen convicted of murder in fire that killed NY cop

NEW YORK (AP) — A teenager who prosecutors say set a mattress fire that killed a New York City police officer and injured another officer has been found guilty of murder.

Eighteen-year-old Marcell Dockery also was convicted of arson and assault charges Thursday after a trial at Brooklyn Supreme Court.

New York Police Department officers Dennis Guerra (GEHR’-uh) and Rosa Rodriguez were trapped in the April 6, 2014 fire and overcome by smoke in the Brooklyn apartment building.

Guerra died three days later. Rodriguez spent six weeks in a hospital.

Dockery testified in his own defense, and said he discovered the fire and tried to save other residents.

In a note announcing the verdict, jurors wrote to the judge that Dockery “didn’t mean to harm anyone” and that they “hope leniency can be shown.”
