A teenager accused of murdering two teachers and two fellow students in a school mass shooting grew up amid domestic violence and addiction and was repeatedly let down by authorities, family members have said.
Colt Gray, 14, is accused of killing four people in a rampage at Apalachee High School in Winder, Georgia, last month in which he shot 11 people, killing four, with an AR-15-style rifle he had been given as a Christmas gift by his father.
