"I got to know [Heather] too well for my own comfort," Casto said. "She popped a lot of pills, she smoked a lot of weed, she drank a lot of alcohol and was a user. To top it off, she would use anybody for anything she possibly could."
Casto said she stopped being friends with Heather shortly after Casto moved next door to her last November. Casto recounted Heather locking her sons in their rooms and leave them for hours.
"You could hear her screaming and yelling at those kids through the walls, cussing them out," Casto said. "They would sit in their bedrooms for hours and hours on end just screaming at the top of their lungs ... she would lock them in their bedrooms because she didn't want to deal with them."
Casto says she knows of three separate people who contacted the Department of Human Services about Heather, but nothing came of it.
"When she wanted the boys to go to sleep she would give them Tylenol, she would give them Nyquil, she would give them numerous things to make them go to sleep at night so they would sleep," she said.
Casto believes Heather intentionally killed her two sons because "she didn't want to be a mother." Meanwhile, Casto waits for justice while mending the heartache over the boys' deaths.
