Community grieves

What they're saying:

Neighbors described Stewart as a warm, funny, and generous man who was married with two daughters. He had lived in the neighborhood for more than 30 years and had recently finished renovations on his home.

"He was the most mild-mannered person and the most helpful in the court," said Stewart's friend. "It's still unbelievable. I look across the street, and I expect him to come out and wave."

Residents said they were shocked by the violence and said that such a crime is unheard of in their quiet, tucked-away cul-de-sac.

" I always call it our little cocoon because usually, nothing ever happens," said the victim's neighbor, Jackie. She wished to withhold her last name.

Residents said the suspect pulled up and waited in his vehicle for a bit before exiting and repeatedly stabbing Stewart, even after the victim was on the ground.

"I haven't digested the fact that he's not here anymore yet," said Jim.
