(Bloomington, Ind.) - The search for a missing Indiana University student continued Wednesday without a trace of her.
Twenty-year-old Lauren Spierer was last seen Friday morning around 4:30 walking home to her apartment in Bloomington.
Investigators say they have suspicions about the vanishing.
“We believe that the chances are very great that there was foul play,” said Bloomington Police Lt. Bill Parker.
The search is gaining more attention. On Wednesday, Indianapolis Colts owner Jim Irsay wrote on Twitter than he will give a $10,000 reward for serious information that solves Lauren’s missing person case.
Although she is an adult, Spierer is now listed with the National Center for Missing and Exploited Children, which has assigned a field officer to assist with the search.
As they have since the disappearance was reported Saturday, a growing number of volunteers searched around the IU campus, Bloomington, and Monroe County Wednesday. Searchers have also been looking around Lake Monroe.
Bloomington Police have been reviewing a security video from Spierer’s apartment. They have also used a lie detector in questioning a male friend who was seen arguing with her that night outside her apartment.
That man, a fellow IU student, told police that they were at his apartment when she left around 4:30 a.m. He watched her walk away without shoes or a cell phone.
Spierer’s boyfriend has also been questioned.
Indiana Excise Police are also investigating Kilroy’s Sports Bar for possibly serving Spierer alcohol the Thursday night before she disappeared, although she is only 20-years-old. It is the last place Lauren was seen in public. Her phone and shoes were found there, police said.
