San Marcos police found 20-year-old Matthew Ellis unresponsive Monday after his friends called 911.

This was the morning after an off-campus event for the fraternity Ellis was pledging.

Since then, all Greek life has been suspended indefinitely.

Every fraternity and sorority at Texas State is under review.

The investigation into Ellis' death could last several months.
