The funeral for 9/11 first responder and retired NYPD detective Luis Alvarez will be held today in Queens.

Alvarez, who became the face of the September 11 health crisis, died on Saturday after a three-year battle with colorectal cancer.

Alvarez was known throughout the community as a fighter – not just through his battle with cancer, but in his fight to ensure that those who worked alongside him on September 11 get the help they need and deserve.

“Before he became a hero across this country, he was always mine,” said Alvarez’s son, David. “He was always a man that I looked up to, who inspired me.”

Alvarez was a father, son, husband, brother, and US Marine. People from all over gathered for his wake on Tuesday in Oceanside, Long Island.

His brother, Phillip, says, “His message is one that is really simple: take care of each other and take care of yourselves.”

Alvarez’s colorectal cancer was linked to the months he spent exposed to the toxins at Ground Zero after the Twin Towers collapsed. The 53-year-old received benefits from the September 11 Victims Compensation Fund, which is in danger of running out of money next month. Alvarez spent his final days fighting for those who need that help.

“You all said that you would never forget. Well I’m here to make sure that you don’t,” Alvarez said directly to a group of legislators.

In his final days, surrounded by family in hospice care, he continued to focus on others.

“We’re trying to get this legislation passed as soon as we can to help other first responders,” said Alvarez.

His family says they’ll make sure his legacy lives on.

“He was at peace and I was at peace knowing he was happy with everything that he accomplished,” said David.

Alvarez’s funeral was held this morning at Immaculate Conception Church at 10 AM where loved ones said their final goodbyes to this national hero.
