More than 130 firefighters battled a fire involving fireworks explosions that engulfed four homes in Pacoima and critically injured a woman on Thursday night, authorities said.

No positive identifications have been made, and recovery efforts are still underway, the county said in a statement.

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.

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.

Fireworks exploded all over the country as the U.S. celebrated the day the Declaration of Independence was adopted.

Getting pictures to share of the fireworks is always a tricky endeavor but there are steps you can take to try and make your photos look great in a tough situation. Rich DeMuro, host of ‘Rich on Tech’ on WOR Sundays,
