JOPLIN, Mo. - Standing amid the ruins of what had been a Goodyear service center, Robert Alves turns in place to take a grim inventory.

That twisted pile next door, he says, was a Jiffy Lube. The shell out back there, a sporting goods store. Over there was a Pizza Hut. And that massive heap across 20th Street used to be the Home Depot.

"Lots of used-to-be's around here," the 36-year-old mechanic says. "ALL used-to-be's."

Even harder to identify is what will be.

The tornado that tore through Joplin Sunday essentially bifurcated this city of 50,000, carving a west-to-east path up to a mile wide that almost beggars description.

"Think about a lawnmower, taking the biggest lawnmower, and just mowing everything down," says Heather Marsh, whose house was in the shadow of the shattered St. John's Regional Medical Center. "It truly makes you feel how insignificant (life) really is. You feel so small and helpless."

Before Sunday, the former mining boomtown was perhaps best known - if known at all to many Americans - as a sometime home base for outlaws Bonnie Parker and Clyde Barrow, and as a stop along Historic Route 66. Now, it is the site of the nation's eighth-deadliest tornado.

At least 125 are dead, and possibly hundreds remain unaccounted for. More than 900 were injured.

On Wednesday, arduous rescue and recovery work went on, with crews repeating grid searches that started immediately after the storm. No new survivors were pulled from wreckage of the city's neighborhoods, but officials said after checking some areas for a fourth time that they planned a fifth sweep. Leaders of St. John's sent in structural engineers to see if the hospital could be saved.

"It truly was like a bomb went off almost on every floor," said Gary Pulsipher, the hospital's chief executive.

Optometrists Justin and Rebecca Stilley had just taken their daughters - Ella and Eva, 3 and 5 - for ice cream and were on their way back to their split-level home in the Cedar Ridge neighborhood on the west end of town. When news of the approaching storms came over the radio, the 36-year-old father did something he'd never done before - he ran a red light.

Sirens were wailing across town when the family reached home. As the girls prepared to go into their "hiding place" - a crawl space with three concrete walls at the back of the garage - Justin Stilley stepped out on the back deck and saw "a big, wide mass" of black, swirling with debris.

Huddled with her children on a plaid blanket beside a drain pipe as the house bucked and rocked above them, Rebecca Stilley recited the Lord's Prayer, over and over.

"Our Father, who art in heaven, hallowed be thy name ..."

When the storm had passed, the Stilleys emerged to find their roof gone, their daughters' bedrooms open to the sky. Justin Stilley's eyes well with tears as he contemplates what would have happened had the twister struck in the middle of the night.

"They wouldn't have made it," he chokes.

Across 26th Street from St. John's Regional Medical Center, Heather Marsh was taking a nap while her 8-year-old son, Hayden, played video games on his Wii. When she heard the sirens, the single mother didn't think much of it; they went off often, and nothing ever came of it.

When they stopped suddenly, she figured it was a false alarm. Then her phone rang.

"Get in the tub!" her mother, Vivian Fannin, was shouting. "Get in the tub!"

Lightning flashed. Then the sirens began sounding again, louder than before.

She gave Hayden a handheld video game, tossed some pillows and blankets into the bathtub and told him to climb in. Suddenly, the little "crackerbox" house she was buying from her parents collapsed around them.

She emerged and surveyed the ravaged landscape. The only identifiable landmark for miles was the windowless hulk of St. John's.

Continuing east and slightly north, the storm raked Main Street and began marching up 20th Street - one of the city's key east-west corridors. Here, the cross streets are named after states, and the damage got progressively worse as the storm passed over Iowa, Indiana, Florida and Mississippi - states that know the destructive powers of nature all too well.

That Sunday, Joplin High School held graduation ceremonies on the campus of Missouri Southern State University. Misty Westfall was driving graduate Amanda, 18, and her brother David, 19, home in her red pickup truck while husband David followed in another vehicle.

When they reached a roundabout, David Westfall continued straight on down to 32nd Street, but his wife decided to take one of her shortcuts.

She took 20th.

Before long, the sky turned inky black and the rain was coming down in sheets. Misty Westfall pulled into the parking lot at St. James Methodist Church, near the corner of Florida.

Suddenly, the truck was being lifted off the ground and rocked violently from side to side. During a brief calm, like the calm in the eye of a hurricane, they heard someone from a nearby house screaming at them to come inside, and they ran for it.

The family took shelter in an interior closet, the only part of the house that would survive.

When the storm had passed, the children went out to help dig survivors from the rubble. Misty Westfall found an old man in an SUV; there was a board protruding from his neck, but she checked for a pulse anyway. There was none.

When David Westfall reached home and his family wasn't there, he picked his way back east along 20th, cutting through backyards. When he found his wife, they locked in a long embrace - and then he lectured her about taking shortcuts.

The Lansaw family was not so fortunate.

Zach Lansaw's home is on 33rd Street, just outside the destruction zone. But his big brother Don lived on Mississippi, right in its path.

After the storm passed, he drove as far as he could, then parked and ran the last half mile or so to Don's little frame house - the center for barbecues and game nights, where everyone gathered to pack for fishing trips. It looked like a box with the sides peeled down.

He found Don on the floor of the back bedroom. He was lying on his back, a green pillow beneath him. He could have been sleeping.

Zach knelt and shook him.

"Please, please, PLEASE. Breathe," he shouted, administering CPR unsuccessfully.

Bethany, Don's wife, told the family that Don had put her in the bathtub and stretched atop her, saving her life.

Don was 31; he owned a machine shop. His mother, Beth Lansaw, visited the wrecked house to try to salvage some mementos. She found a wedding photo, some quilts her mother had sewn for the boys, and a battered VHS tape of Don's high school graduation.

Mrs. Lansaw had brought her two boys up in the Pentecostal church. Don had strayed some, had his troubles with drinking. But about three months ago, he'd told her that he'd found a new church home over in Carthage, that he and Bethany had answered an altar call, had been prayed over and experienced the laying on of hands.

She is sure he is in heaven. But that doesn't lessen the pain.

"I just don't understand why," she says, sobbing on a log in the soggy grass out back. "Why him? And I won't know that until I'm there with him - there with our maker, to ask him why. I'm not blaming God. No. Don wouldn't want me to. I know he wouldn't."

The storm continued its march up 20th, crossing Range Line - the major north-south road that eventually becomes part of Route 66 - and flattening the Home Depot. Search and rescue teams have spent days poking holes in collapsed concrete slab walls to allow the dogs to sniff out the living and, as the days wore on, the dead.

Just up the road, a couple hundred yards from the city limits, Alan Gouge stands beside what is left of the Pepsi warehouse that had been his "second home" for the last 33 years. The 47,000-square-foot metal building that shipped more than 3 million cases of soda last year had been reduced to a 20-foot pile.

Standing atop the foundation, the 51-year-old warehouse manager was astonished to be able to look west and see the hulk of St. John's, about six miles distant.

"You never could do that before," he says. "All the trees are gone. All the buildings are gone. And you just look back west, and it's total destruction. It's hard to imagine."

It is both a blessing and a cruel irony of such storms that when they cut a path through a city, they often leave large sections on either side unscathed. Brent Blizzard, whose grandmother died and whose parents' home was destroyed, finds it both troubling and comforting that he can go just a few blocks from the Goodyear station where he worked and get a burger or a latte.

"That's what makes it so surreal," he says during a break from pulling waterlogged radials from the twisted heap. "It's hard to wrap your head around."

Buildings are missing. And so are people.

Sitting on a flatbed outside the shell of Joplin High, new alumna Sarah Sticklen cannot begin mourning for her alma mater until she learns what happened to one of her best friends.

Will Norton, a kind of local celebrity who parlayed his YouTube stardom into a paying gig and an offer of admission from Chapman University, was ejected or sucked from his father's car on the way home from graduation. Authorities have searched for him in hospitals in three states and are not yet sure of his fate.

"I haven't been able to really fathom it yet and weigh it all in," the 17-year-old says.

Looking around, it is hard to imagine how the mountain of wreckage can ever be cleared away, let alone rebuilt. But Vince Martinez is confident that it will be.

Martinez, 68, is no stranger to devastation. He served with the 3rd Marine Division in Da Nang during the Vietnam War.

Martinez's Marine Corps Active Wear on 20th is a total loss, what's left of his stock drying in the parking lot. But the former staff sergeant says Joplin residents should take heart from the words on his shirt. Semper Fi: Always Faithful.

"They'll survive, just like any other city in this country," he says. "This is the United States. You can take THAT one to the bank."
