Fraternity suspends Texas A&M chapter after student's drug overdose death

COLLEGE STATION, Texas – The Sigma Nu fraternity has suspended all activities of its Kappa Sigma chapter at Texas A&M University following the death by drug overdose of a member last weekend.

A fraternity statement Thursday announced the suspension while an investigation into the death of 19-year-old Anton Gridnev of Frisco takes place.

College Station police determined Gridnev died of a drug overdose last Saturday at the fraternity house.

Authorities have not released what drug Gridnev ingested.

Four students have been arrested on drug-related charges.

KPRC-TV in Houston reported Michael Frymire, 20, and Samuel Patterson, 21, have been charged with possession of a controlled substance.

Ty Robertson, 21, and Christian Sandford, 18, have been charged with possession of marijuana. Others were also cited with possession of drug paraphernalia.

The executive director of the Virginia-based fraternity, Brad Beacham, says Sigma Nu officials are cooperating in the investigation. 

The fraternity also suspended the membership of the four suspects. The Texas A&M chapter was founded in 1985.
