If she knew one of the tenants was struggling financially, she would bring them a box of food. When Hernandez’ car broke down, her husband helped him find a replacement.

Detectives were on scene for hours collecting evidence. They believe the people responsible for the shooting, had broken into other cars.

“It’s very upsetting to see this happened to her,” said Evelyn Murillo, Linda’s neighbor.

She said she heard the commotion but didn’t realize her acquaintance had been killed.

Murrillo said Linda was the kind of person who went out of her way to help other people in the neighborhood and that she didn’t deserve to die like this.

“If someone would need something, she’d hear about it and then she’d go confront em, you know? If there’s a way she could help. She was a very special person.There’s hardly people like that nowadays.”
