MINEOLA - The ex-con accused of gunning down a Nassau police officer and a father of four before staging his own shooting appeared in court today.

Darrel Fuller allegedly shot officer Arthur Lopez during a traffic stop following a hit-and-run on the Cross Island Parkway last year. Investigators say that after killing Lopez, Fuller fled the scene and then fatally shot Raymond Facey so he could steal his car and flee to Queens.

Police arrested Fuller several hours later, but he has yet to go to trial for his alleged crimes. Fuller's attorney has recused herself from the case because she says she can't provide the kind of trial experts that Fullers' case requires. Fuller has retained a new lawyer, who was not available to speak to News 12 today.

Fuller was in shackles as he appeared in court for a hearing today, where he faced a sea of officers in blue uniforms who were there to support their fallen colleague.

Fuller previously served four years in prison after pleading guilty to attempted murder back in 2005. A competency hearing is scheduled for Oct. 15 to determine if he is psychologically fit to stand trial.
