Ultimately, while Garrett said he couldn't rule out Spierer's friends, he moved on to another lead. Tipsters suggested Spierer could have owed money for drugs to an alleged member of the Sons of Silence motorcycle club. Ross went to his door hoping to speak, but was rebuffed.

Garrett then looked into a new lead generated from a website maintained by Spierer's parents. The tip suggested former IU student Corey Hamersley could have information about Spierer's disappearance.
Hamersley, currently serving a prison sentence for firing shots at police officers near Bloomington's campus in 2012, agreed to speak with Garrett – but said he didn't know anything about Spierer's disappearance and didn't want to be associated with the case.

Though Garrett hasn't yet solved Spierer's disappearance, he believes he's close -- the investigator says he thinks he's just one interview away from finding the answers to the case that has haunted Bloomington for half a decade.
