QUEENS - A sea of blue made its way through Rockaway Beach as mourners bid their final farewells to the NYPD officer who lost his life after responding to a Coney Island fire.  

Thousands of fellow NYPD officers and firefighters joined family and friends to honor fallen officer Dennis Guerra at the Saint Rose of Lima Church. The 38-year-old husband and father of four is being remembered as a great cop, and an even better person. 

Guerra succumbed to his injuries at Montefiore Medical Center in the Bronx Wednesday after he and his partner, Rosa Rodriguez, were overcome by smoke and carbon monoxide during a high-rise fire last weekend. Rodriguez remains hospitalized in critical condition. 

Police have arrested 16-year-old Marcell Dockery, who they say started the blaze because he was "bored." He faces a number of charges, including felony murder and arson, and could be sentenced to 25 years to life in prison if convicted. 

Mayor Bill de Blasio was among those who spoke during the funeral service. Guerra is the first NYPD officer killed in the line of duty since 2011.
