Louisville mass shooter's brain to be tested for CTE and family plans CTE test due to multiple concussions and mental health concerns.

The brain of Louisville mass shooting suspect Connor Sturgeon will be tested for CTE, a degenerative brain disease found in those with a history of repetitive brain trauma. Sturgeon allegedly killed five people and injured eight others in Monday's mass shooting at Old National Bank. Former NFL player Phillip Adams, who carried out a mass shooting in 2021, had CTE at the time. Sturgeon's family said he had mental health challenges, but there were no warning signs he was capable of the act.
