The Nassau County Conviction Integrity Unit investigates all allegations of wrongful conviction. The Conviction Integrity Unit began investigating claims of the wrongful conviction of Christopher Ellis in August 2019, who was convicted after trial in 1993 of murder in the second degree, two counts of attempted robbery in the first degree, two counts of criminal possession of a weapon in the second degree, two counts of criminal possession of a weapon in the third degree, and one count of criminal possession of stolen property in the third degree.
The Conviction Integrity Unit investigative team reviewed the Nassau County Police Department’s case file, which revealed certain memo-pad notations made by a detective after the September 29, 1990, murder of Joseph Healy. The memo-pad entries relate to leads the police received about two other potential suspects of the crime who the police ultimately declined to charge.
These memo-pad notes were not contained in the District Attorney’s file, and further investigation revealed that they had never been turned over to the defendant or the two co-defendants as required under Brady v. Maryland. Upon discovery, the Conviction Integrity Unit promptly disclosed the notes to Mr. Ellis’ attorney, Ilaan Maazel.
The NCDA has no basis to believe that the failure to disclose the notes was intentional, or that the prosecutor was even aware of their existence. The Conviction Integrity Unit was unable to confer with the former prosecutor because he passed away in September 2018.
Along with the murder of Mr. Healy, Ellis was convicted of an attempted robbery in Freeport. The conviction as it relates to those charges has not been disturbed.
The NCDA has not made a determination whether Mr. Ellis will be retried for the homicide of Mr. Healy.
Our condolences remain with family and friends of Joseph Healy, as well as his many friends and colleagues at Hofstra University.
