ALLENTOWN, Pa.—Officials are planning to release details regarding the investigation into the death of Garrett Reid, the son of Philadelphia Eagles coach Andy Reid.

Northampton County District Attorney John Morganelli is holding a press conference Thursday afternoon.

Garrett Reid was found dead in his dorm room on Aug. 5 at Lehigh University in Easton, where he was assisting the team's strength and conditioning coach during training camp.

He was a recovering drug addict who had seemingly turned his life around. But Andy Reid has indicated that his 29-year-old son may have had a relapse.
