Investigators on Sunday announced that they had located the epicenter of the tragic West fertilizer plant explosion . Assistant Texas Fire Marshal Kelly Kistner said investigators would be working inward from the least to most damaged areas as the search continues for the cause of the blast but provided no timeline for a report on the incident.

On Saturday, a problem with a tank at the plant cause several small fires, which were extinguished by Sunday.

Also Saturday, residents of the least-damaged areas were allowed to return to their homes, but there was no water, electrical or gas service still. There was a curfew of 7 p.m. remaining in effect for the area. It was unknown when residents of other areas would be able to return to their homes.

Four more of the first responders who died in the blast were identified on Sunday, including brothers Doug and Robert Snokhous, of the West Volunteer Fire Department; Jerry Chapman, Abbott Volunteer Fire Department; and Kevin Sanders, who worked with the West EMS and a another local volunteer fire department.

A memorial service is scheduled for Thursday to honor the 14 people who died in the explosion.
