An ex-convict accused of fatally shooting an Albuquerque police officer last month has pleaded not guilty to violating federal firearm laws.
Prosecutors say 34-year-old Davon Lymon was arraigned in federal court Tuesday.
He was indicted by a federal grand jury last week and remains in federal custody pending trial.
Lymon was arrested several hours after Officer Daniel Webster was shot multiple times during an Oct. 21 traffic stop outside a pharmacy.
The 47-year-old former Army Ranger died eight days later in a hospital, having suffered gunshot wounds to his upper body and jaw.
Authorities say Lymon has been in and out of the court system for years and pleaded guilty more than a decade ago to voluntary manslaughter.
The Albuquerque resident was facing misdemeanor battery charges when Webster was shot.
