BELLEVUE, Iowa (AP) - Sandie Crilly was helping her 8-year-old

son, 12-year-old niece and 2-year-old granddaughter pick up Tootsie

Rolls from the ground during Bellevue's annual Fourth of July

parade when someone yelled to get out of the way.

Looking up, she saw two panicked horses dragging a carriage

charging toward them.

"I could see it was two horses," said Crilly, 46, of Willow

Springs, Ill., who was visiting her parents in Bellevue. "I could

see they were running at full speed and they were harnessed

together and I knew we were going to most certainly get hit, and as

soon as it happened, everybody was crying and screaming."

Someone pulled her granddaughter to safety, but Crilly said her

niece broke her wrist and lost her two front teeth. At least 22

other people were injured, some critically, and one woman was

killed, police and hospital officials said.

Janet Steines of Spragueville, whose husband was driving the

carriage, died Sunday evening at the University of Iowa Hospital in

Iowa City, according to the Hachmann Funeral Home in Bellevue.

The horses got spooked after they rubbed heads and one's bridle

fell off, police said. They galloped for several blocks through

downtown Bellevue, a town of about 2,300 residents along the

Iowa-Illinois border. The wagon overturned at some point, dumping

its four passengers.

Many of the injured were children like Crilly's niece who were

picking up candy from the street that had been tossed to them.

Most of the injured were treated at hospitals and released, but

at least four people remained in critical condition late Sunday and

several others were seriously hurt, according to police and

hospital officials.

Paramedics treated victims at an art gallery in town and a

triage area was set up near the Mississippi River, where volunteers

held up tarps to shield the injured and paramedics from the sun and

heat, Crilly said. Others brought the injured ice and water, she

said.

"It was madness," Crilly said. "I mean we were in a triage.

The town really came together. It was a huge community effort."

Mayor Virgil Murray said residents were shocked, and they've

never had problems with having horses in the parade before.

"We've never really had any tragedy," the mayor said.

"Usually our biggest nemesis is if it rains. That's what we're

always worried about."

Between 3,000 and 4,000 people attend the parade, many people

coming in from rural areas and nearby towns, he said.

The injured were sent by ambulance and medical helicopter to

hospitals in Dubuque, Maquoketa and Iowa City. Ten patients were

taken to Mercy Medical Center-Dubuque, nine of them children, house

supervisor Carol Dietzel said.

Two children in critical condition was flown to University of

Iowa Hospital, and one was in fair condition at Mercy Medical, a

hospital official said. Seven children were treated and released.

Iowa Gov. Chet Culver released a statement saying the victims

were in his thoughts and prayers.

"I am especially saddened because the accident occurred during

the events celebrating Independence Day, which is a day that should

be filled with pride and joy for all Iowans and Americans," Culver

said.
