Long lines of cars streamed by West's community center, dropping off food, water and other rations throughout the weekend. Numerous church groups and restaurants handed out hot meals.
"These are our neighbors. They are coming to help," Waco Police Department Sgt. William Patrick Swanton told reporters. "You will find that in Texas. You will find that across the United States. We put everything aside when it comes to these types of situations."
The cause of the fire and explosion has not been determined yet, but investigators have isolated the center of the blast, Assistant State Fire Marshal Kistner said Sunday. The explosion left a large crater in the middle of the distributor, Kistner said.
Funeral arrangements are pending for those killed.
