Police said Monday that Gridnev was a fraternity brother who had recently moved into the home, and his permanent address was listed as Frisco. News 8 has learned he graduated from Frisco Heritage High School.

"Our hearts are filled with sorrow as we grieve the loss of this young man," said Sigma Nu Executive Director Brad Beacham. "Our thoughts, prayers and deepest condolences are with his family and loved ones. We appreciate the immediate support and care the Texas A&M community is providing during this very difficult time."

While investigating his death, officers found illegal narcotics and drug paraphernalia in some of the fraternity house's rooms, which led to the arrest of four brothers.

Samuel Patterson, 21, of Nacogdoches, was charged with possessing Ecstasy and LSD. Michael Frymire, 20, of Dallas, was charged with possessing THC. Both could face 180 days to two years in jail and a $10,000 fine.

Christian Sandford, 18, of Houston, and Ty Robertson, 21, of Grandbury, are charged with possessing marijuana. They could face up to 180 days in jail and a fine of $2,000.

Gridnev's death is still under investigation. According to a probably cause statement released by College Station police, fraternity brothers told arriving officers that Gridnev had taken "some kind of opioid."
