WATCH: Doctor Claims He Knows Why O.J. Simpson Might Have Killed Nicole Brown Simpson and Ron Goldman

The brain doctor who discovered Chronic Traumatic Encephalopathy (CTE), also known as the football disease, says the condition may explain why O.J. Simpson might have murdered Nicole Brown Simpson and Ron Goldman.

Is it really possible that Simpson’s 11 seasons playing for the NFL could have led him to double homicide?

According to Dr. Bennet Omalu, CTE is caused by traumatic impact to the cranium. This causes protein buildup to accumulate in the brain’s blood vessels which can moderately to severely impact the victim’s cognitive functions.

Dr. Omalu told BuzzFeed that this can lead to increased aggression and violent behavior. Other symptoms of the disease include depression, mood swings, and criminal tendencies.

Unfortunately, there are no visible symptoms, and the only way to diagnose the disease is by actually cutting into the brain after death to see it.

Get the full details on this shocking hypothesis in the video above and decide for yourself, could football-related injuries have acted as a catalyst to double murders—and does justify it if it did?

Simpson was acquitted in the murder trial for his ex-wife and friend in 1994, but he is currently serving a 33-year prison sentence for multiple armed robbery and kidnapping felony charges from 2007.
