CORVALLIS, Ore. -- It's been a week since 16-year-old Ava Carey went missing in Corvallis and on Thursday, police announced other law enforcement agencies are joining the search.
The Corvallis Police Department said law enforcement agencies across the mid-valley are getting invovled, including the FBI.
Ava's mother, Cecelia Carey, said this week has been the hardest week of her life.
"Night is really hard. I think, where's Ava sleeping? Where's my girl? Did she eat? Is she scared? Who has her?" Carey said.
More than 60 people gathered at a park across the street from Cheldelin Middle School where Ava was last seen. People placed messages on what is being called the "Wall of Hope." A pastor also said a prayer that Ava will be found safely.
On Wednesday the Corvallis Police Department launched an online tip form specifically for Ava.
Carey said Ava's face is popping up along the West Coast. People are putting up posters, yard signs and five billboards have Ava's face on it, she said.
"We have community members, people we haven't met in different states, who are at their own expense printing flyers and taking time to go hang them up," Carey said. "It's remarkable."
Police are holding a press conference Friday with another update on the search. The date and time are still to be determined.
