An investigation into the fatal heroin overdose of Garrett Reid, the oldest son of Philadelphia Eagles coach Andy Reid, revealed there were steroids in his room the day he died, a Pennsylvania prosecutor said Monday.

Northampton County District Attorney John Morganelli said that anabolic steroids were found in the room where Garrett Reid was staying when he overdosed on heroin Aug. 5 during Eagles training camp. Reid was helping the team’s strength and conditioning coach at the time of his death.
