A woman, 40, and her two-year-old child were killed in a fall at Petco Park less than an hour before the start of Saturday afternoon's San Diego Padres - Atlanta Braves game.

Police told reporters the deaths "appeared to be suspicious" but it was too early to determine if they were accidental or intentional.

The incident occurred on Tony Gwynn Drive in the Gaslamp Quarter. The woman and child fell from the concourse dining area at the third level of Petco Park, the equivalent of about six stories.
