Brian Michael Beltran was arrested Wednesday in Fresno, Calif., where records showed he was also held at the Fresno County Jail on a probation violation pending a court appearance and his transfer in custody to Nevada.
In Las Vegas, Beltran faces charges in the slaying of 23-year-old Kenneth Mallet about 8:30 a.m. Monday.
Police haven't said what led to the shooting. But witnesses said Mallet argued with his assailant before he was fatally wounded at a complex on Smoke Ranch Road near Tenaya Way.
Mallet was pronounced dead a short time later at University Medical Center in Las Vegas.
