The Brooklyn teen who set a mattress on fire, sparking a blaze that killed an NYPD officer, was sentenced to 19 years to life in prison Tuesday.

    
Dockery was convicted of murder last month after a jury trial for the April 6, 2014, inferno inside the 13th-floor hallway of the high-rise in Coney Island that killed Officer Dennis Guerra.  

Marcell Dockery was convicted of murder last month after a jury trial for the April 6, 2014, inferno inside the 13th-floor hallway of the high-rise on Surf Avenue in Coney Island that killed Officer Dennis Guerra.

"A senseless act of arson cost a very courageous police officer his life and destroyed the health and career of another heroic officer" said Brooklyn District Attorney Ken Thompson. “The sentence imposed by the court today reflects the severity of the crime committed by the defendant.”

Guerra died three days after he and his partner Officer Rosa Rodriguez were engulfed by a dark cloud of smoke responding to the fire. Rodriguez suffered permanent damage to her lungs.

"The family acknowledges that when Marcell Dockery set fire to the mattress he didn't mean to hurt anyone that day — but others suffered by his actions," Guerra's widow Cathy Guerra said in a victim impact statement given in Brooklyn Supreme Court Tuesday.

Kathy Guerra requested that Brooklyn Supreme Court Justice Danny Chun give Dockery "the help he needs" for his "history of arson."

The heartbroken widow tearfully told the judge that her children continue to suffer without Guerra, who was not only their father but a role model and friend.

Prosecutor Howard Jackson recommended sending Dockery to prison for 18 years to life, noting his lack of remorse and his repeated accusations of the NYPD coercing a confession from him.

Dockery will be sentenced to two years in prison for the robbery that will run together with his murder conviction.
