On Tuesday, the small, sparsely stocked shop on General Courtney Hodges Boulevard had the feel of a hunting outpost: fishing rods, salt licks, eight shotguns mounted on a pegboard wall. A vintage refrigerator brimmed with worms and maggots for fishing. The sound of crickets, sold out of a large box in the back, filled the store as customers passed over its blue carpeted floor in a steady flow, mostly buying bait for less than $2.

“Bait alone doesn’t make you rich, but bait keeps people coming back,” said Nell Little, the sister-in-law of the 76-year-old owner, Clarence Little, who, she said, was gone until Saturday. “Just an old country store, I don’t know what to tell you.”

She said the family knew before the shooting on Saturday that some of the guns stolen in 2011 had ended up in New York. The one used in the shooting, she estimated, would have sold for $300 to $385. She said she was sad to hear about Officer Moore, who was 25, and she said Mr. Little was selling fewer and fewer guns as he prepared to sell the store and retire.

“It’s bad any way you look at it,” Ms. Little said.

In New York, the Police Department and the Patrolman’s Benevolent Association said on Tuesday that a wake for Officer Moore, the son of a retired police officer, would be held on Thursday in Bethpage, on Long Island, near the family home in North Massapequa. Then the police funeral, with its thousands of officers in rows of blue uniforms, will be held on Friday in St. James Roman Catholic Church on Long Island, the same church where officers mourned Edward R. Byrne, a rookie officer shot dead in 1988, also in Queens.

Evidence in the killing of Officer Moore was to be presented to a grand jury on Tuesday as Queens prosecutors sought a first-degree murder indictment against Demetrius Blackwell, 35, who grew up in the same corner of Queens Village where, the authorities said, he killed Officer Moore. One of Mr. Blackwell’s cousins, who also lived in the neighborhood and went on to play football for the New York Giants, said on Tuesday that he was “devastated” by the killing.
