Brother of NFL quarterback among 2 fatally stabbed at Nashville nightclub

Beathard was the brother of San Francisco 49ers quarterback C.J. Beathard and musician Tucker Beathard, according to the newspaper. He also was the son of country music songwriter Casey Beathard and the grandson of Bobby Beathard, the NFL executive who was inducted into the Pro Football Hall of Fame in 2018.

Trapeni attended Rhodes College, according to a Facebook post by the school’s student government.

A 21-year-old man also was stabbed and remains hospitalized with injuries to his arm and eye, WZTV reported.

Police identified three men and a woman as persons of interest Saturday night, according to the television station.

“The fatal stabbings appear to have resulted from an argument over a woman that began inside Dogwood Bar and then turned physical when the parties went outside,” the Metro Nashville Police Department said in a news release. “Multiple persons were involved in the outdoor fight during which the two men were both fatally stabbed in their sides.”

Clayton and Trapeni graduated from Battle Ground Academy, in Franklin, in 2016, WZTV reported.

In a statement, Beathard’s parents said they were overwhelmed by the support they have received from people.

"It's times like this I wish had Instagram and social media because the love and prayers have been so overwhelming," Beathard's parents, Casey and Susan Beathard said in a statement to The Tennessean. "We cannot possibly thank you at the rate they come in texts and phone calls. Clay was an amazing, big and soft hearted human being with an undeniable love for the Lord. He had his family's, friends' and teammates' backs even to a fault. I wish he would have been more inclined to take the high road but he hated 'wrong.'"
