Northampton County District Attorney John Morganelli and Coroner Zachary Lysek held a press conference Thursday to share their findings.
Interviews revealed that Reid, 29, was found slumped over in a chair on the morning of August 5. An Eagles team physician attempted to revive Reid with a defibrillator. A used syringe and spoon were found in the room. Toxicology tests later confirmed Reid had injected heroin.
Evidence recovered from the scene suggests that Reid was in possession of a large amount of syringes and needles, as well as 19 vials of an unknown liquid substance and other drug paraphernalia.
There were no findings of foul play. However, Morganelli said that the investigation will continue as they try to identify anyone who may have "facilitated" Reid by delivering illegal drugs to him either in Northampton County or Philadelphia.
Both Morganelli and Lysek said that they have received full cooperation from the Eagles.
"These results sadly confirmed what we had expected all along," Andy Reid said through a statement. "We understood that Garrett’s long-standing battle with addiction was going to be difficult. He will, however, always have our family’s love and respect for the courage he showed in trying to overcome it. In the end, we take comfort in our faith and know that he’s in a better place. We miss Garrett. We miss his smile, his laugh, and his energy and we will forever love him.
“There are many other individuals and families engaged in this struggle in their own lives, and they will always have our support, encouragement, and understanding. Never give up!”
Garrett Reid was assisting the team in the strength and conditioning department and and had accompanied the Eagles to training camp. He was found dead in a Lehigh University dorm room on August 5.
The Reid family released a statement the following day that suggested Garrett's death was drug-related.
Some 900 people, including dozens from the NFL community, attended Garrett's funeral in a grand show of support.
The players have dedicated the season to Garrett.
