Convicted killer of Providence Detective wants new trial

In a 15 page handwritten filing, convicted killer Esteban Carpio says he lacked "criminal responsibility" for stealing Providence Police Detective Sgt. James Allen’s gun and firing the fatal shots that killed him back in 2005.

Carpio representing himself in this latest court battle writing, "I was suffering from mental illness and proved that, at the time of the crimes. I could not appreciate the wrongfulness of my conduct or conform my conduct to the law."

The 38-year-old shot Detective Sgt. Allen at Providence police headquarters were he was being questioned for the stabbing of an 84-year-old woman.

Now, 11 years after his conviction he says he wants them vacated and a new trial.

Carpio says his lawyers provided ineffective counsel.

"My trial lawyer was not familiar with R.I. Rules. Therefore, he did not file the appropriate motions so the insanity defense issue could be argued on appeal,” said Carpio.

The President of the Providence Police Union, Robert Boehm  issuing this statement on the matter; "Carpio with professional legal representation and facts presented to a jury was found guilty of murder of a police officer. Although we as law enforcement respect the process for appeals, we see no reason why this appeal would be upheld."

Col. Hugh Clements telling ABC 6 News, “Once a case is adjudicated and it’s a legal fight, we rely on the AG.”

Carpio is serving a life sentence in Connecticut.
