(CNN) The brother of the gunman who killed 17 people at a Florida high school says he wants to dedicate himself to ending bullying, and that he believes bullying contributed to his brother's actions. On February 14, Cruz's adopted brother Nikolas opened fire at Marjory Stoneman Douglas High School in Parkland, Florida, claiming the lives of 17 students and faculty. Zachary Cruz previously told investigators he bullied his adopted brother Nikolas when they were younger, according to a Palm Beach County Sheriff's report. Cruz told reporters he used to fight a lot with his brother when they were younger, but that they "made amends" and grew closer in their teenage years. When asked what he hoped to do there, he said, "Finish high school, work on this bullying thing that I want to do, and just live my life."
