Investigators are piecing together the profile of 23-year-old Robin Westman, identified as the gunman who opened fire during a school Mass at Annunciation Catholic School in Minneapolis, US on Wednesday. The attack left two children dead and 17 others injured according to the Associated Press (AP), before the shooter was found dead from what police believe was a self-inflicted gunshot.According to Minneapolis Police Chief Brian O’Hara, Westman was armed with a rifle, shotgun and pistol, and fired dozens of rounds through church windows where children were seated for Mass around 8:30 am local time.Police said Westman had legally purchased the weapons and acted alone, with no prior criminal record.
