NEW ORLEANS (WVUE) - The 17-year-old man accused of killing a father and son inside their Metairie home was in Orleans Parish Criminal Court Friday for an arraignment.
Earlier this week, prosecutors charged Dexter Allen with attempted second-degree murder and armed robbery, among other crimes.
He pleaded not guilty.
Investigators accuse Allen of leading U.S. Marshals on a chase and nearly hitting one marshal back in April.
The same week, in Jefferson Parish, authorities say he shot and killed David and Nicholas Pence in their Metairie home.
The Orleans Parish District Attorney's Office filed a bill of information Wednesday formally charging Allen with four crimes, including attempted second-degree murder and armed robbery with a firearm.
Investigators say Allen carjacked a woman in St. Roch hours before allegedly killing the father and son. And as U.S. marshals tried to arrest Allen a few days later, they say the teenager try to run over a deputy marshal.
Haraquon Degruy, 18, was also charged in the Pence case. She is accused of driving the getaway vehicle.
