The remains of at least some of the seven who are missing have been found at the site of Tuesday's deadly fireworks warehouse explosion in Yolo County, Calif.

H uman remains have been found at the warehouse filled with fireworks that exploded in Northern California this week, officials said. The number of fatalities was not released and no positive identifications have been made, Yolo County officials said. Seven people were considered missing on Wednesday.

Rescue crews were searching on Thursday for seven people still missing days after an explosion at a fireworks warehouse in Northern California shook a tiny farming community and forced the cancellation of nearby July Fourth celebrations.
