Christopher Clements, 36, faces 22 charges in relation to the disappearance and murders of the young girls.
Celis family neighbors on the eastside say the latest development in the years-long case gives them a sense of relief, but not quite closure.
Ashley Toth remembers how scared she and her roommate were right after the 6-year-old went missing in 2012.
"We were scared. My roommate got an alarm system hooked up, almost... I think within a week or two after that. Just because we were nervous, you know, having a little girl living in the home. Of course it made us all paranoid. Everyone in the neighborhood I think was pretty nervous, especially people who have children in the home," Toth said.
