Levine mentored Christina Grimmie when she finished third on NBC's The Voice two years ago. Grimmie's New Jersey hometown held a candlelight vigil on Monday night to honour the 22-year-old killed Friday night as she signed autographs after a show in Orlando. Authorities say she apparently had no personal connection to the man who shot her.
