WEST, Texas -- Residents are trying to get back to normal, following last week's massive fertilizer plant explosion. The blast has left at least 14 people dead and 200 others injured. Most of the dead were firefighters and emergency medics.
The powerful explosion at the fertilizer plant has forced hundreds from their homes. Now, residents who live on the perimeter of the blast zone have been allowed to return.
From the outside, some homes appear unscathed, but on the inside, it tells a different tale.
"It looked like nothing was wrong, then you walk in and it was just... all the ceilings were down, all the insulation, just everything," said Susan Matus.
The damage to homes in the area is widespread. But some say the property damage is minor in comparison to what they could have lost.
"We have our health. We were fine. There are so many people who don't have anything," said Rae Turner.
John Klander says, "This is just material. Even if it leveled it as long as my family was safe and they were. I could care less if its tore up. I lost friends out there just like everyone else in this town did."
Some schools in the area have also reopened, as the town takes steps towards returning to everyday life. Meanwhile, investigators are still trying to determine what caused the blast.
Officials say the process will take some time.
"We do not have a timeline as to when the investigation is going to be complete. It is a very slow methodical process. But it is continuing. We're working at the right pace to make that we get the job done, and that we get it done correctly," explained Assistant State Fire Marshal Kelly Kistner.
President Obama is scheduled to attend a memorial service for victims of the plant explosion on Thursday. The event will take place at Baylor University.
