Colin Gray testifies in trial after his son was accused of Georgia high school shooting

The father of accused school shooter Colt Gray has taken the stand in one of the latest cases in which parents are being put on trial after their children are accused in fatal shootings. Defense lawyers called Colin Gray to testify shortly after court began early Friday as they begin presenting their case. Prosecutors say he should be held accountable for giving his son the weapon used in the shooting as a Christmas gift despite alleged threats and warning signs that the boy was mentally unstable.
