MIAMI — Nikolas Cruz's semiautomatic rifle may have jammed during the massacre at a high school in Parkland earlier this month, according to Miami Herald news partner CBS4. Cruz then dropped the AR-15 and fled with other students, CBS4 reporter Jim DeFede tweeted Tuesday afternoon, citing three sources familiar with the investigation.
