Olga Galdemez, 42, and her daughter Jaylin Landaverry, 17, were working inside their food truck, La Parrillada Chapina, at 3rd Street and Wyoming Avenue when the 100-pound tank blew around 5:30 p.m. on Tuesday. The truck was equipped with two such tanks filled with gas.

Investigators believe propane vapor began leaking from one tank and filled the truck. A flame from the grill inside the mobile restaurant provided the spark, officials said. Witnesses told detectives they smelled gas before the blast.

The propane fueled a fireball that engulfed the truck, the street and surrounding sidewalks. One tank was blown 95 feet away into the backyard of a home nearby, police said.

Galdemez's husband spent 20 minutes at the scene of the explosion on Wednesday morning talking with investigators from the Philadelphia Police Department, the Philadelphia Fire Department and the Bureau of Alcohol, Tobacco and Firearms. The truck was properly licensed to operate, officials said.
