PENSACOLA, Fla. – A Florida man has been sentenced to 20 years and three months in prison for being high on drugs when he caused a crash that killed two siblings. Hunter Black, 26, was sentenced Tuesday in Escambia County circuit court after pleading no contest to two counts of DUI manslaughter and one count of marijuana possession, the Pensacola News Journal reported. The other vehicle’s driver, Antoinette McCoy, 22, and her brother, Sean Banks, 15, were seriously injured in the crash. The siblings were airlifted to a Pensacola hospital, where they died, officials said. An analysis of his blood sample, taken after the crash, revealed the presence of Xanax and cannabis in his system, prosecutors said.
