FREMONT -- A pair of teenage boys charged in connection with a smash-and-grab robbery at a Newark mall jewelry store in July pleaded not guilty Monday.
Rodney Askari Rederford, 16, of Oakland, and Jamal Darcel Walker, 17, of Hayward, appeared in court before Superior Court Judge Dennis J. McLaughlin at the Fremont Hall of Justice. Both are in custody and were ordered by the judge to return to court Nov. 26 for a preliminary hearing.
Alameda County prosecutors have charged both boys as adults.
A third suspect, San Francisco resident Raymond Jefferson Jr., 20, remained behind bars at the San Francisco Jail on Monday, authorities said. A court date had not yet been scheduled for him, court records show.
A fourth suspect is still being sought.
Prosecutors last month charged the trio with armed robbery, assault with a deadly weapon, burglary and false imprisonment for the July 26 incident, court papers show.
Authorities say the suspects were among four robbers who stormed Zena Jewelers International in the crowded NewPark Mall in Newark, smashed display cases with a pistol, grabbed jewelry and fired shots in the shop.
A probable cause affidavit shows the men held employees at gunpoint.
No one was injured in the 12:15 p.m. armed robbery, which left broken glass and shell casings littering the store's floor.
The four suspects -- who police said were each armed with a gun -- ran to at least two waiting getaway cars after the robbery and reportedly headed onto northbound Interstate 880 in a white Mercedes E-class and a black Acura or Lexus, police said.
Police have not released what type of jewelry was stolen or its estimated value.
The store, which opened in 2010, carries rose gold jewelry, opal and custom jewelry and estate jewelry.
Police are asking anyone with information on the heist to contact Newark police at 510-578-4237.
