Junior Seau's Death a tragedy- Is CTE the cause?

Junior Seau, a homegrown superstar who was the fist-pumping, emotional leader of the San Diego Chargers for 13 years, was found shot to death at his home Wednesday morning. He was 43.

Police Chief Frank McCoy said Seau’s girlfriend reported finding him unconscious with a gunshot wound to the chest and lifesaving efforts were unsuccessful. A gun was found near him, McCoy said, and police were investigating the possibility that Seau’s death was a suicide. Police said no suicide note was found and they didn’t immediately know to whom the gun was registered.

It starts with behavioral and mood disorders like depression. It can include thoughts of suicide, loss of impulse control or flair ups of temper
