Katie Suarez, the Brooklyn jogger who was callously killed by a crazed ex-cop, was remembered Thursday as a welcoming, loving and joyful person who led life with a smile.

Family, friends and neighbors dressed in purple — her favorite color — said their final goodbyes to the young woman at the Church of Sts. Simon and Jude in Gravesend, less than two miles from where she was fatally knifed during an evening run.

Anguished cries erupted several times during the heartbreaking service, as Rev. Edwin A. Ortiz urged Suarez’s loved ones to remember the friend she had been rather than the callous way she was killed.

“She was someone who we looked for. She would be someone who we wanted to be with and talk to and laugh with. Katie was one of those that will be unforgettable,” Ortiz reflected.

“Will we remember Katie simply because of how she passed? Or will we remember her and honor her in the way she treated others, in the way she welcomed others, in the ways she took time to get to know others? Her sense of humor, her patience, her ability to listen to others, and to give advice.

“We can only focus so much on how she passed, but we will miss the point. Katie truly was a gift from God and truly someone who brought us together. We can never forget that.”

Suarez’s family did not deliver remarks during the service, which Ortiz oversaw in both Spanish and English.

The young woman’s parents — who found her crumpled body after Sayed Mohassib allegedly attacked her — have been publicly demanding justice for their daughter, who they described as an “angel.”

Instead, Ortiz shared his own memories of Suarez, 28, who he said treated him like “family” — and greeted everyone with a smile.

“There was a joy and peace behind that smile,” Ortiz said.

“We, too, must together continue what Katie taught us: to smile, to greet, to be kind, to be charitable, to be loving and to be faithful. If we learn nothing else, let us simply remember how Katie treated others and how she treated us.”

Suarez will be laid to rest at Green-Wood Cemetery.

Hundreds of mourners had attended Suarez’s wake at Cusimano and Russo Funeral Home the night before, with one heartbroken loved one writing “Goodbye, sweet angel” on a memorial board.

One woman broke down in front of the open casket, weeping: “Katie! Katie!”

Jerry Rivera Jr. expressed guilt that Suarez was alone when the maniac set his sights on her — saying the Empire State Family Motorcycle Team typically spends evenings at the promenade, but wasn’t there on that fateful night.

“That really bothers us. A lot of us have kids of our own. I have a daughter myself. The fact that we were not there and could not help her,” said Rivera, 28, who did not know Suarez personally.

Others railed against the lack of lighting on the path where Suarez was killed, saying the city should install more cameras and police in the wake of the tragedy.

“Can you imagine, your child goes for a run and doesn’t come back?” grieved a woman who gave her name as Magdalena.

“Now we have officers there. It’s too late. She will never come back.” 

Dozens of loved ones and neighbors released balloons “to Katie” before the wake near the water at Caesar’s Bay, where she worked as a TD Bank teller.

Suarez’s alleged killer has said he doesn’t remember lunging and stabbing her in the neck as she ran along the Belt Parkway on Oct. 30.

She succumbed to her injuries two days later — but saved the lives of five others through organ donation.

Mohassib, who was booted from the NYPD and the US Marine Corps over mental health concerns, somehow landed a job with the Department of Education, working part-time starting last March, before getting a full-time gig as a paraprofessional this year despite his troubling history.
