Michael Mosley was arrested on Christmas Day in Nashville, according to USA Today. Mosley, 23, was arrested after a days-long search and is facing two counts of criminal homicide and one charge of attempted homicide.

Clayton Beathard, 22, and Paul Trapeni III, 21, were stabbed outside of The Dogwood Bar in Midtown Nashville early Saturday morning. A third person,  A.J. Bethurum, 21, was also stabbed, and was taken to Vanderbilt University Medical Center.

Beathard played football at Long Island University and Battle Ground Academy. Beathard was also the brother of country music star Tucker Beathard. His father is country music songwriter Casey Beathard, and his grandfather is NFL Hall of Famer Bobby Beathard, a scout with the Atlanta Falcons from 1968-71 and a senior adviser after Arthur Blank purchased the team in 2001.

Beathard also won four Super Bowls as a general manager.

The day before his capture, Mosley was added Tuesday to the Tennessee Bureau of Investigation's Most Wanted list.

Police said the fatal attack started as an argument "over an unwanted advancement made by a man toward a woman in the bar," said a statement from Nashville police. The woman was a friend of the victims, police said.

Surveillance video retrieved by police detectives showed four people involved in the altercation, which began in the bar as a verbal dispute before spilling outside and then across the street, police said.
