Ali Ahmed Mohammed died outside DC9 on Oct. 15 because of cardiac anomalies, alcohol, and a physical struggle, a report just released by the Office of the Chief Medical Examiner says.

Mohammed’s death was ruled a homicide in the report, but he wasn’t—as police alleged the night of the incident—beaten to death by DC9 employees. The official manner of death, according to the report: “Excited Delirium Associated With Arrhythmogenic Cardiac Anomalies, Alcohol Intoxication and Physical Exertion With Restraint.”

The U.S Attorney’s Office has issued the following statement about the findings:

The Medical Examiner has now completed an autopsy related to the unfortunate death of Ali Ahmed Mohammed.  The Medical Examiner’s forensics examination has concluded that a variety of factors led to the death of Mr. Mohammed, and we intend to carefully study these conclusions as part of our legal analysis of this tragic incident. Our deliberate and comprehensive factual inquiry continues, and we again express our sincere appreciation to the family of Mr. Mohammed for their patience and understanding as we work to reach a just conclusion to our investigation.

Attorneys for the DC9 employees originally charged with murder in the incident—though the charges were later dropped—couldn’t immediately be reached for comment.
