According to Lanter's obituary, he was a 2002 Carmel High School graduate where he played football and baseball. Carmel High School football coach John Hebert told The Star he had coached Lanter since he was about 12. "He was quick and tough and ran hard," Hebert said of the running back. Lanter graduated from IU's Kelly School of Business with honors before landing a job as a trader for Goldman Sachs in New York in 2007 after a short stint at ThinkEquity in San Francisco. In 2011, Lanter left Goldman Sachs to attend the University of Chicago's Booth School of Business where he earned an MBA. He briefly served as a consultant for Angelo, Gordon & Co. in New York before starting his own consulting company earlier this year.
News reports indicate that Lanter entered the Chatterbox shortly before midnight last Friday and initially argued with the bar's owner, David Andrichik, about paying a $7 cover charge before being admitted to the bar. The situation quickly escalated after bar personnel determined Lanter was too intoxicated to serve any alcohol. Lanter and another man at the bar got into a scuffle. The other man allegedly struck Lanter, causing him to fall and hit his head. By the time police arrived, the man involved in the altercation with Lanter had already left the bar. Police have since identified the man and interviewed him, although it's not clear yet what he told to police.
One rumor that has been circulating is that Lanter was actually struck by a member of the jazz band that was performing at the Chatterbox that night. The band was reportedly taking a break when Lanter arrived that night. According to that rumor, the band member was trying to be helpful to the bar's management after Lanter became upset about not being served alcohol. Earlier news reports indicated that Lanter lost his balance and fell after being struck by the other man in the neck area. Lanter was believed to have struck his head on the bar according to news reports, although another account Advance Indiana has heard says he struck his head on the edge of the raised stage where the band played.
