A New York Giants safety who once played for San Diego State University announced on Twitter that his cousin was among those killed Wednesday in the San Bernardino, California, mass shooting.
Nat Berhe tweeted Thursday morning that he had learned his cousin was one of 14 killed when two people opened fire inside a San Bernardino state-run social services facility on Wednesday. Gunfire erupted during a holiday party, and many of the victims were county employees, including Berhe's cousin.
"I am so sick right now," Berhe tweeted.
Later in the afternoon, he identified his cousin as 60-year-old Isaac Amanios, of Fontana, California. According to The Associated Press, Amanios worked for the county as a supervising environmental health specialist.
Berhe went on to share that his parents work at the building adjacent to where the shooting occurred. The player implored his followers to keep the families of the victims in their thoughts.
Berhe, 24, played defensive back for the San Diego State Aztecs from 2010 to 2012. He led the team in tackles his final year. The Colton, California, native is currently on the injured reserve list with the New York Giants after suffering a calf injury. He has not played since last season.
Twenty-one people were injured in Wednesday's massacre, which authorities said was carried out by a husband and wife. Their motive remains unclear, but intelligence sources have told NBC News the husband had contact with extremists under FBI observation and may have been radicalized.
