JOPLIN, Missouri (AFP) - Officials said Thursday they have identified just one of the 125 bodies pulled from the rubble after a massive tornado struck Missouri, but said they managed to narrow the list of missing to 232. Some of those missing from Sunday's disaster may be among the unidentified remains being stored in a hastily constructed mass morgue, but officials cautioned that the list could change if more missing persons reports are filed, or as more bodies are identified. "There may be family members that have not come in and filed a missing persons report," Missouri deputy director of public safety Andrea Spillers said. She also said that of the 232 missing, "we can't presume that all of those are deceased." explaining that some people may simply have not checked in with their families or authorities. Joplin was virtually wiped off the map by a monster twister which roared through the town late Sunday causing a wide trail of destruction. Authorities pleaded with anxious family members for patience while they undertake a lengthy identification process involving DNA testing and fingerprinting. Asked why families were not being allowed into the morgue to visually identify their loved ones, Spillers said such visualization "is not 100 percent accurate, and 100 percent accurate is our goal." Among those reported missing were at least 15 people from area nursing homes, and several groupings of family members form the same address. They included five members of the Merritt family who lived on South Day Road: Nevea, age two or three; Payton, age five; Alexandria, age eight; Allen, 26; and 28-year-old Brittany. Also still missing is Wil Norton, the 18-year-old who was sucked out of his father's Hummer as they were driving home from his high school graduation. Don Bloom, a member of the Federal Mortuary Response Team assisting in recovery operations, defended the decision to engage in a lengthy identification process, stressing that despite pressure to speed up the process, "the process has to take its time." One problem slowing the process: medical records that could be used to identify some of the bodies were lost when St. John's hospital was destroyed in the twister. Officials urged residents who know of the whereabouts of anyone on the list to call in, and said they hoped that by publishing the 232 names, they could locate the missing and ease the frayed nerves of their anxious loved ones. "Our goal is to get that number to zero," Spillers said. "We will dedicate as much state resources as needed, around the clock, to make sure that all the family members who have loved ones they cannot find are connected."
