Ahmad Al Aliwi Alissa opened fire in a store killing 10 people. But Ahmad’s family claimed he was mentally ill.
Ahmad was arrested by the police and charged with 10 counts of murder.
The scrutiny of his social media posts revealed his hatred for anyone who even remotely criticised Islam.
His brother Ali described him as a very kind and genteel boy who became antisocial after being bullied in 2014 for being a Muslim.
In the wake of the second mass shooting in a week, US President Joe Biden advocated tough measures to check the sale of weapons.
Ahmad and his family migrated to the US from Syria in 2002. More weapons were recovered from his house in Colorado.
