Man accused in Metairie double murder faces second obscenity charge for actions in jail _lowres

Dexter Allen (New Orleans Police Department)

A teenager who police believe gunned down a father and son inside their Metairie home in April pleaded not guilty Friday to related charges including attempted murder across the parish line in New Orleans.

Attorney Jerome Matthews entered a plea of not guilty on behalf of Dexter Allen, 17, for the Orleans Parish charges, which stem from a crime spree that allegedly occurred before and after the murders. The charges are attempted second-degree murder, armed robbery, illegal possession of stolen property and unauthorized use of a motor vehicle.

Authorities say Allen stole a white Toyota Highlander from a woman in New Orleans East on April 22 before shooting David and Nick Pence on Clifford Drive in Metairie. After Allen killed them with a shotgun, police said, he was tracked to New Orleans, where he almost mowed down a U.S. marshal with his car on the same day, leading to the attempted murder charge there.

Allen wore a white cross around his neck during his Friday appearance in front of Criminal District Court Judge Keva Landrum-Walker. He did not speak.

The woman authorities say was his accomplice, 18-year-old Haraquon Degruy, is being held in Jefferson Parish Correctional Center on a count of principal to second-degree murder.
