Story summary

Griffin John, who was released from prison early after serving 48 months for attacking his wife Shauntai Nickerson, killed three children and a teacher at Silver Rail Elementary School in Bend, Oregon. The attack occurred last Thursday when he used his mother's shotgun to enter the school and target his former special education classroom, fatally shooting 5-year-old Rhoam Summer, an 8-year-old student, an 11-year-old student, and teacher Megan Lambert, 25.

Court documents revealed that Griffin John’s father had a history of domestic violence against Nickerson before Griffin John II was born. His father threatened her with a knife and had multiple arrests for alcohol abuse, leading to several stints in jail. Despite this background, Griffin John pleaded with a judge to lift the restraining order so he could see his son grow up in Newport, Oregon.

The elder Griffin John’s letters to the court highlighted his violent past and addiction issues, indicating a troubled family history that may have contributed to the shooter's actions.
