While the cause of death is being investigated, Doyle Brunson wrote in a blog post today that it was a prescription drug overdose.

It seems like yesterday when my nephew called and gave me a message that made my blood run cold, “I think Chip just died” he told me.

It happened again yesterday, only this time it was Chip’s only son, Casey Reese. Casey was found in his apartment from an apparent overdose of prescription drugs. I had seen Casey a few days ago and he looked great. He was very handsome and extremely personable. I will always remember the closeness between Chip and Casey.

My deepest condolences to the Reese family. I feel like I’ve let Chip down but I don’t know what I could have done to help Casey.

Few details about a presumably sad occurrence, but Casey was 20, had a promising baseball career, and likely would’ve found his way to poker upon reaching legal casino gambling age, where we would’ve watched to see if he would indeed become the Dale Earnhardt Jr. of Poker.

The unconfirmed word on the street is that it was from a drug overdose … and it seems plausible enough, as the untimely death of a father can often send someone down such a path.
