Police are investigating after a 70-year-old woman was killed inside her Queens home early Tuesday morning.

Eva Usher got a phone call early Tuesday morning, telling her that her mother had been shot in her home.

"They told me somebody was banging on both doors, and she probably thought it was one of the kids, so she opened and, 'What the hell?', and then shot her. They just shot her dead," Usher said.

Leta Webb was shot in the head and arm at around 1:40 a.m. The 70-year-old was rushed to Jamaica Hospital, where she was pronounced dead.

Webb lived in the neighborhood for 45 years, raising children and providing foster care.

Eva Usher said one of the children her mom adopted and raised is serving time for murder, and that she believes this is a case of gang retaliation.

"Whoever got to the door first and just opened, they shot them," Usher said. "And that's what the detective was saying, that it was a hit. She was the first one at the door."

Longtime friend Joan Hall had just spent the evening with Webb Monday night at her sister's house nearby. She was in disbelief that her friend was gone.

Hall: She's so good to everybody. Everybody. Leta don't do nobody nothing.
Clark: Do you have any idea why anybody would want to do this to her?
Hall: No. That is what I'm shocked. I'm shocked. How could anybody want to do something to Leta? Leta is always doing for people.

"Very nice lady. Very, very nice," said Margaret Chrysostom, Leta Webb's friend. "You couldn't have a better friend."

Eva Usher said she was confident whoever was responsible would be apprehended by the police.

"People talk, so it's going to come out. It's going to come out," Usher said. "There's too many people out here. Somebody's going to say something to somebody, and it always happens like this. Somebody's going to say something to somebody. They're going to catch them. I believe it."

Usher remembered backyard barbecues at her home and her mother doing what she could to keep her kids off the streets. She said the house was like a day care for everybody, run by a woman who will be missed on 119th Avenue.
