Chris Benoit's seven year old son Daniel suffered from a contition known as Fragile X Syndrome, which is a form of mental retardation and autisic type behavior.
Also reported by People, Chris's doctor said he didn't appear troubled or upset when he met with him prior to last weekend. He said, "He was in my office on Friday to stop by just to see my staff. He certainly didn't show any signs of any distress or rage or anything. I'm still very surprised and shocked, especially with his child Daniel involved."
In the past, his doctor prescribed him testosterone, because his levels were low. Probably caused from steriod use. He would not say if he prescribed him any medication before last weekend.
Police are still searching for a motive. The investigation still continues.
