Lacy Alderete says she can't help but watch her 7-year-old boy a little bit more than normal.
"I think it changes the way you parent," Alderete said as she placed another poster of Jessica Ridgeway in her neighborhood. "It does scare you a bit when it is this close to home."
Posters with the girl's photo on them continue to go up around Westminster.
"The more people helping the better," Volunteer Coordinator Joshua Sikora said. "Yet, you'd be surprised to know just how many people don't know [Jessica] is missing."
On Wednesday, investigators, with a number of neighboring agencies, conducted sweeps of the neighborhood where Ridgeway was last seen.
Officers could be seen peering into car windows, looking into trash cans and looking over fences. Some of the investigators were seen carrying brown paper bags.
The front door of Ridgeway's Westminster home holds one of the many posters scattered around the neighborhood.
"When something like this happens, you want to feel useful," Alderete said. "It's every parent's worst nightmare. I think if it were me, I would want people to do everything they could to bring my child back."
