A 78-year-old businessman who was allegedly operating the boat that killed a teenage ballerina is speaking out. Carlos Guillermo Alonso’s attorney says he had no idea that an accident had occurred. Alonso’s boat was discovered by investigators after a three-day search docked outside his luxury waterfront home in Coral Gables. Ella Adler was killed while water skiing on Mother’s Day weekend. Alonso has not been charged and is said to be cooperating with the investigation.
