Authorities announced on Monday that the FBI had recovered a surveillance video they believe was intentionally deleted. They say it showed that Tim was given at least 18 drinks in the 82 minutes before he fell 15ft (4.6m) down the steps of the fraternity house's basement.
But it would take about 12 hours before any of his fraternity brothers called emergency services.
While horrific, this incident is not isolated. Three other students at different US universities have died since Tim's death - two in the last couple of weeks.
All four students who died this year were reported to be new members (or "pledges"). The selection process for "rushing" applicants can sometimes last months, and provisional members do not know if they will be made a full member.
"This creates a power imbalance where the older members can tell them what to do," Hechinger explained.
Research showing alcohol and hazing related deaths are nothing new, but data shows fatalities appear to be on the increase.
As their popularity and membership levels have risen, universities have been able to use them as a way to draw in prospective students. While they are largely independently funded through donations and student contributions, colleges sometimes offer subsidies and incentives like cheap leases on properties.
