The mother of Deion Patterson, the man accused of shooting five people in midtown Atlanta, said he was angry that doctors wouldn’t give him Ativan, an anti-anxiety drug. Patterson, a Coast Guardsman who had been discharged in January, suffers from apparent mental health issues. He is charged with one count of murder and four counts of aggravated assault. One woman was killed and four others were wounded in the shooting. Three of the victims remain in critical condition.
