Authorities are continuing to investigate the circumstances that led to the death of a woman and injuries to her two sons after they slammed into the Old Seven-Mile Bridge on Monday evening while parasailing.

The mother was killed in the incident, and a severely injured son was eventually taken to a hospital in Miami. The other son had only minor injuries, according to the Florida Fish and Wildlife Conservation Commission. The accident occurred shortly after 5 p.m. on Monday, according to law enforcement agencies.
