JERSEY CITY, N.J. (CBSNewYork) – Mourners are paying their respects Monday to the police detective shot and killed in the Jersey City shootout.

A wake is being held Det. Joseph Seals.

Services began at 2 p.m. at the McLaughlin Funeral Home on Pavonia Avenue in Jersey City. There has been a massive show of support from the law enforcement community. Friends, family and fellow police officers all gathered to say goodbye.

Lines formed early outside the funeral home. Hundreds of mourners waited in the cold to pay their respects to Det. Seals, and his family.

Det. Seals was killed in the Bay View Cemetery, ambushed by the same two people who went on to murder three more innocent civilians in a kosher market a mile away. Seals is being remembered as a hero, and as a husband and father of five kids.

“Thank God for the men and women in law enforcement that are willing to pay the ultimate sacrifice,” said chaplain Greg Boyle.

Seals’ colleagues and supervisors remember him as a cop’s cop, a hard worker, and one of the most instinctive officers on the job.

He gave his life protecting Jersey City. That sacrifice won’t be forgotten.

“Many, many thousands of people will be here today. Many, many thousands of people will pay him honor tomorrow. Our law enforcement community will never forget him,” Boyle said.

The funeral is on Tuesday at 10 a.m. at Saint Aedan’s: the Saint Peter’s University Church, on Bergen Avenue.

Sunday night, a sea of people filled the streets in Seals’ hometown of North Arlington, N.J., to honor the life of the 40-year-old.
