WEST -The death toll from the powerful fertilizer plant explosion Wednesday night in West rose to 15 on Monday.
A source close to the investigation confirmed that one of the people injured in the explosion died at a hospital, but had no other details.
Meanwhile, authorities say they are conducting a "slow and methodical" search of the site of the massive plant explosion.
Officials on Monday did not update previous figures of at least 200 injured in last week's blast in the town north of Waco.
They are allowing residents who live on the perimeter of the blast zone -areas known as "Stage 1" and "Stage 2" - to come back to their homes. People who live closest to the site are not allowed in yet.
Assistant State Fire Marshal Kelly Kistner says officials are still investigating how the explosion occurred as volunteer firefighters were working to put out a fire.
West Mayor Pro Tem Steve Vanek says restoring water and natural gas to the whole city could take weeks.
