The family of Georgia school shooter Colt Gray threatened to go ‘full throttle’ after the 14-year-old was charged as an adult for murdering four people on Wednesday.

Gray’s relatives leapt to his defense within hours of him opening fire at Apalachee High School, where he allegedly killed four people and injured nine others.

The teenager’s aunt, Annie Polhamus Brown, took to Facebook during the aftermath, bringing up the issues he ‘dealt with’ and saying she ‘will take care of my nephew and what he needs on this side.’

‘Just check yourself before you speak about a child that never asked to deal with the bull**** he saw on a daily basis,’ she said in the posts, which have now been deleted.

‘Y’all ready to see Polhamus blood in full throttle? Nah, I wouldn’t either.’

The social media posts sparked fury as tributes poured in for the four victims in the tragedy, teachers Christina Irimie and Richard Aspinwall, and students Mason Schermerhorn and Christian Angulo, both 14.

Authorities say they are still investigating how Gray was able to bring an AR-style weapon inside his school, with footage of the aftermath appearing to show the weapon on the floor as terrified students were escorted down hallways to safety.

As parents and police raced to the school in Winder, Georgia, Polhamus Brown took to Facebook to plead for help in contacting the Georgia Bureau of Investigation.

‘Please someone get me in touch with GBI!!! I’ve tried calling!’ she wrote, following up with: ‘I am not scared, I will not back down.’
