VIDEO: Man Indicted in Shooting of NYPD Officer, May Pursue Insanity Defense

The man accused of killing an NYPD officer was indicted on 12 criminal counts, including aggravated murder, in Queens Thursday, reports WABC.

Demetrius Blackwell, 35, pleaded not guilty at his arraignment inside a courtroom packed with more than 200 officers in death of police officer Brian Moore, and his attorney indicated that he may pursue an insanity defense.

Earlier, Queens District Attorney Richard Brown announced the results of the grand jury probe, saying "The defendant's alleged actions are a direct attack on society and the law and reminds us of the dangers that our police officers face each day."

Blackwell continues to be held without bail. The indictment charges him with one count each of aggravated murder, second- and first-degree murder, attempted aggravated murder, second- and first-degree attempted murder, second- and third-degree criminal possession of a weapon, seventh-degree criminal possession of a controlled substance, unlawful possession of marijuana, petit larceny and fifth-degree criminal possession of stolen property. The first-degree murder charge carries a penalty of life in prison without the possibility of parole.

Moore, 25, died on May 4 at a Queens hospital, two days after being shot in the head. Authorities said Blackwell fired three times, hitting Moore in the face.
