On February 14, 2018, a gunman opened fire with a semi-automatic rifle at Marjory Stoneman Douglas High School in Parkland, Florida, killing seventeen students and staff members and injuring seventeen others. Witnesses identified Nikolas Cruz, a nineteen-year-old expelled student, as the assailant. Cruz fled the scene on foot by blending with other students. He was arrested without incident about an hour later in nearby Coral Springs. He confessed to being the perpetrator, and he was charged with 17 counts of premeditated murder and 17 counts of attempted murder. Police and prosecutors have not offered a motive and are investigating "a pattern of disciplinary issues and unnerving behavior", but Cruz offered several motives for the crime.
