(Daytona Beach, FL) -- Three children are safe after their pregnant mother drove her minivan into the ocean at Daytona Beach. The woman was hospitalized for a mental health exam Tuesday after rescuers pulled her and the three, nine, and ten-year-old kids from the van. Authorities are looking into the incident, but it's possible that a medical emergency could have caused the woman to lose control of the vehicle. It's also possible that's not what happened, as one witness told Florida's WESH 2 TV that one of the kids was screaming about their mother trying to kill them. The children were taken by a relative in Orlando.
