Nashville police seeking suspect in fatal stabbing of two men, including brother of San Francisco 49ers quarterback

Police in Nashville have identified a suspect in the stabbing death of Clayton Beathard, the younger brother of San Francisco 49ers player C.J. Beathard, and another man.

Arrest warrants were taken out Monday night against Michael D. Mosley, 23, charging him with two counts of criminal homicide and one count of attempted criminal homicide, the Metro Nashville Police Department reported. Police say Mosely is a danger to the community and they are asking for the public’s help in locating him.

Clayton Beathard, 22, and Paul Trapeni III, 21, were stabbed and killed during a fight early Saturday outside the Dogwood Bar.

Speaking at a Monday news conference, police spokesman Don Aaron said the investigation shows Mosley made unwanted advancements toward a woman who was a friend of the victims.

A verbal dispute occurred inside the bar, which led to physical fight outside the bar, Aaron said. It appears Mosley, armed with a sharp object, stabbed the victims, he said.

Beathard and Trapeni were stabbed in their sides and taken to Vanderbilt University Medical Center, where they died, police said. Autopsies showed the men died of stab wounds, Aaron said.

Another 21-year-old man who was stabbed was hospitalized with wounds to his eye and arm, according to a news release from the Metro Nashville Police Department. His identity has not been released and his condition was not immediately known.

Police had posted a photo of a man taken by a surveillance camera and asked for help identifying him.

Police said Mosley was among the four people wanted for questioning in surveillance video released this weekend. One woman and one man from the video have been interviewed, but a man wearing a Nike sweatshirt has not been located, according to Aaron.

C.J. Beathard missed the 49ers game Saturday night because he was traveling to Nashville, a statement from the team said. The 49ers beat the Los Angeles Rams 34-31.

“I spent an hour with him last night and he was exactly like any one of us would have been, distraught, struggling to talk,” head coach Kyle Shanahan told the players in a postgame speech that the team shared on Twitter.

C.J. Beathard is the No. 3 quarterback on the San Francisco 49ers depth chart. He has played 13 games in his three-year NFL career.

According to the San Francisco 49ers media guide, the Beathard brothers performed in local talent shows growing up with C.J. on lead guitar. Clayton, who was known as Clay, also played guitar. Brother Tucker Beathard played drums. He is now a country music singer with one Top 10 hit to his name.

Their father, Casey Beathard, has written hit songs for Kenny Chesney and Trace Adkins.
