Marvin Norwood, 32, was arraigned Thursday on a charge of a felon being in possession of firearms. Police discovered rifles and handguns in Norwood's attic during the investigation of the assault case in 2010.
Police recovered two semiautomatic rifles; a 12-gauge shotgun; a .45-caliber semiautomatic pistol; a .357-caliber revolver; and ammunition.
A federal jury returned an indictment against Norwood and co-defendant Louie Sanchez last week. Sanchez was also convicted in the assault of former Santa Cruz paramedic Bryan Stow.
Stow sustained permanent brain damage from the assault that occurred after a baseball game in 2010.
Sanchez is currently serving an eight-year sentence in state prison for that conviction. Norwood served two years of a four-year plea deal for his part in the assault and was set to be released when the indictment was returned, and he was rearrested.
Norwood was ordered held without bail by a federal judge last week. The trial is scheduled for April 29. Norwood faces a statutory maximum sentence of 10 years in federal prison if convicted.
Sanchez has not yet entered a plea in the federal weapons case.
Sanchez had previously been convicted of the felony of evading an officer and the misdemeanor of infliction of corporal injury to spouse/cohabitant. Norwood had previously been convicted of a felony charge of infliction of corporal injury on a spouse/cohabitant.
