Golden provided this deposition after his release from prison, on December 22, 2008.

Andrew Golden committed a school shooting with Mitchell Johnson in 1998. Golden was eleven years old at the time of the attack. In 2000, he appealed his conviction, focusing on issues of competency to stand trial and whether or not juveniles can use insanity as a defense.

Because Mitchell Johnson was only 13 years old at the time of his school shooting, he could only be imprisoned until age 21. Following his release, he was arrested in 2007 for possession of marijuana and a firearm. In 2009, Johnson appealed the case.

 On April 2, 2007, nine years after his attack, Mitchell Johnson gave this deposition.

This case is not connected to Johnson’s rampage attack. After he was released from prison for the attack at age 21, he was subsequently arrested for possession of marijuana and firearms. In this case he is appealing his conviction.
