Four male students from Case Western Reserve University in Ohio died in a plane crash on Aug. 25. Now, one of the student's family members are considering filing a lawsuit against the Zeta Beta Tau fraternity and the flight club that rented the plane to the young men (via Daily News).

Student Abraham Pishevar's family believes the flight was a part of ZBT's recruitment process and has filed a petition for discovery. The petition asks for receipts of financial transactions for rush activities from the chapters of the fraternity and other documentation. The family hopes to gather evidence and decide if they want to pursue a civil lawsuit.

However, the fraternity denies the flight was part of recruitment.

But, Pishevar took photos the night of the flight and sent them to friends, referencing fraternity rushing.

Along with 18-year-old Pishevar, William Felten, 19, and Lucas Marcelli, 20, also died in the crash. They were members of ZBT. The fourth victim was 18-year-old John Hill.
