A 21-year-old University of Cincinnati student's disappearance since early Sunday has stumped police in Ohio, ABC News reported.
Brogan Dulle vanished Sunday after reportedly leaving his apartment to go look for his cell phone. On Thursday, some $20,000 in rewards was being offered as search for the missing student expanded.
Dulle, who was last seen at a pizza pub near campus, was headed back to his apartment at about 2 a.m. Sunday when he realized he lost his cellphone.
Surveillance video released on Thursday shows him using a flashlight to try and find the phone as he retraced his steps. According to the Washington Times, he never returned home and hasn't been seen since then, officials confirmed.
Every lead in the disappearance has been looked over and exhausted by the department, Cincinnati Police Lt. Col. James Whalen said.
"We have no evidence of foul play at this point," Whalen said. "It's unusual that we don't get a phone call. Somebody saw something."
Although police stated that there was no reason to suspect foul play, Dulle was described as being very responsible by friends and family members. His phone remains missing as well, according to the Washington Times.
The last few days have seen volunteers hold a massive search by passing out fliers, looking in homeless shelters and canvassing the woods, with friends and family leading the way.
"A member of the UC family is missing," UC President Santa Ono said. " ... We want him back home and at UC."
More than $13,000 has been raised to help fund search efforts. Online, more than 16,000 have joined the "Help Find Brogan Dulle" Facebook page, posting videos and photos of Dulle in happier times, ABC News reported.
"Brogan, we just want to talk to you, man. We just hope you're alright," Ernst, a friend, wrote.
Courtney Knowles Hass, Dulle's cousin, said the family is humbled by the public support.
"Each painful day that passes is eased by the love and support we are seeing in each one of you," she wrote online.
