Two children died Sunday evening after running into oncoming traffic on SR-78 trying to retrieve a suitcase that had fallen off the GMC Yukon they were riding in, according to the Vista Fire Department. "Our understanding was that the mom was driving with kids, and a piece of luggage got displaced from the vehicle and landed in the freeway," said Bret Davidson, Vista Fire Operations Chief. "She pulled over to the side of the road, and two of the children exited the vehicle and went into the freeway and were hit at freeway speeds as they tried to retrieve the luggage." The incident happened at 6:10 p.m. in the eastbound lanes of SR-78, east of Mar Vista Drive.
