Monge's family said it feels as if time has stood still since Kenia disappeared.
"It's not a regular day for me anymore," Kenia's sister Kimberly said. "The weeks that go by, they just don't feel like weeks, they feel like years and ages."
"It's a helpless feeling," her stepfather, Tony Lee, said. "We're totally helpless."
But even through that pain, the family said they still maintain hope.
"Day by day, God has given me the strength and I know God will bring her back," Kenia's mother, Maria Lee, said
But new evidence against a man named Travis Forbes raises a lot of questions about where Kenia may be.
Search warrants involving Forbes include witness statements describing a group of people burning something in a barrel outside the bakery where Forbes works the night Kenia disappeared.
Forbes was also spotted on camera wearing latex cleaning gloves that went up to his elbows.
"It's surreal," Forbes said. "I don't even know what to think of it."
Forbes said he didn't do anything wrong.
"If I had known that she was going to go missing, I wouldn't have left," he said.
In fact, Forbes said he wishes he would have done more to keep her safe.
"I could have intervened more and not just said like 'okay' and gone home," Forbes said.
Monge's family said they're just happy there is new information in the case. They said it brings them one step closer to seeing their daughter again.
"I know the police and the detectives are helping us and I know we are going to find her because God is with us," Maria Lee said.
Monge's family said they've been putting up missing persons posters and reaching out to people through Facebook to learn more information, but they said they have yet to receive any solid leads.
