Mayor Bill de Blasio held a moment of silence for Guerra and ordered flags lowered to half-staff across the city Wednesday in honor of the fallen officer. Meanwhile, memorial ceremony was held at One Police Plaza, and included a helicopter flyover in Guerra’s honor.

He called Guerra “exemplary” and said “we will honor his sacrifice.”

“We’ve lost a good man this morning — a very brave police officer, Dennis Guerra, who did something that most of us wouldn’t understand how to do,” de Blasio said. “He went selflessly towards the flame, selflessly towards those who are in danger, no matter what the risk to him.”

Speaking before hundreds of officers as flags were lowered in the plaza of police headquarters, Bratton said “the entire city grieves this terrible loss.”

“Police Officer Guerra gave his life trying to save others and that is the ultimate selfless act,” Bratton said.

Guerra’s colleague, 36-year-old Rosa Rodriguez, remained Wednesday at the burn unit at Weill Cornell Medical Center. Rodriguez is a single mother of four kids and a four-year veteran of the NYPD Housing Bureau.

CBS 2 was told Rodriguez was making steady progress in hopes of a full recovery.

“We pray that every young person who hears of the tragic passing of hero police officer Dennis Guerra and of the suffering of officer Rosa Rodriguez and their families, learns that there [are] deadly consequences that result from foolish actions,” PBA president Patrick Lynch said in a statement. “Our thoughts and prayers are with the Guerra and Rodriguez families, friends and their fellow officers.”

Thirteen others were also injured in the blaze, including three firefighters.

Rodriguez’s sisters attended the ceremony honoring Guerra at One Police Plaza, even as Rodriguez herself struggled to survive her injuries.

“Today is a very sad day for the NYPD – Officer Guerra’s family,” Lynch said. “but it’s also a day of hope that Officer Rodriguez’s family is standing in front of a hospital the day she walks out — and we applaud rather than cry.”

But on Wednesday, the tears were flowing for Officer Guerra, and police badges were banded in black.

Guerra never regained consciousness after thick smoke overwhelmed him during the fire.

“He went selflessly towards the flames; selflessly towards those in danger no matter what the risk to him,” Mayor de Blasio said. “Our hearts go out to the Guerra family. We will stand by them. We will stand by them in their grief and beyond.”

On Wednesday, the NYPD planned to file felony murder charges against Dockery. Police said he confessed to starting the fire on the 13th floor of the high-rise because he was bored.

One neighbor called Dockery a “good kid” and said he was not a troublemaker. But another resident of 2007 Surf Ave. told police Dockery menaced her with a razor a few months ago.

Dockery had also been arrested before when he was 13 for allegedly setting a fire in school. He had other sealed arrests for minor charges as a juvenile.

In the fire that killed Officer Guerra, Dockery has been charged with arson, assault and reckless endangerment.

PBA President Lynch had no sympathy for Dockery as he honored the officer whose life was lost.

“A kid like that, who is bored, needs to realize every action there’s a reaction and that reaction sometimes is life or death,” he said. “In this case, it was death. It’s not a free ride, he should pay. He murdered a New York City police officer and we won’t forget that.”

Officers Guerra and Rodriguez were overcome by smoke and carbon monoxide while responding to Sunday’s fire. They were hit by a wall of smoke when they reached the 13th floor by elevator.

On radio transmissions, the officers could be heard gasping for air.

The FDNY was just minutes behind them. Bratton said firefighters found the officers “unconscious and unresponsive” in the hallway.
