It's been a week and a half since anyone's seen Tyler Allen, but his friends and family are trying to stay positive. However, with every passing moment, their faith is being tested.
"It really means a lot to our family and we're so grateful," said Lindsay Allen, Tyler's sister, before breaking down into tears.
For the second straight day, Allen's parents searched for their son in Boulder. This time, they were joined by volunteers at a park where the 20-year-old spent a lot of time.
Police say there's no sign of trouble at the apartment Allen shares with roommates and he sent a text message to a friend last week saying he's alright.
But his bank account hasn't been touched and he doesn't have access to a car or a bike.
"We're trying to stay strong and just make sure he comes home," said Sheryl Allen, Tyler's mother.
While Wednesday's search turned up nothing, his parents know the entire Boulder community is pulling together for Tyler.
"It's not just our search efforts, it's really the police and the community and students it's everybody, everybody out there is looking for him and we're just so grateful for that," Sheryl Allen said.
Another vigil is planned for Thursday night at the Presbyterian Church of Western Springs.
His parents say they aren't giving up hope of being reunited with their son. In fact, they are planning on searching more areas including music venues and other state parks.
