Jeanne Mack, grandmother of the U.S. student jailed in the Cayman Islands for violating quarantine laws, speaks out on ‘America’s Newsroom.’ The grandmother of a Georgia college student who was jailed in the Cayman Islands for failing to follow coronavirus quarantine guidelines told Fox News on Monday that she has written to President Trump seeking the U.S. government's help in the case. Jeanne Mack made the remark ahead of an appeals court hearing Tuesday for Mercer University student Skylar Mack and her boyfriend, Cayman Islands-based competitive jet-skier Vanjae Ramgeet, who each have received four-month sentences. "She’s terrified. She called me last night, she couldn’t sleep," Jeanne Mack told Fox News when asked about the hearing.
