Gunman Kills 1 in Utah Hospital Siege : Standoff: He gives up after holding nine hostages, including three infants, in maternity wing for 17 hours. Explosives are found by police.

A man claiming to have explosives shot and killed a nurse Saturday, then barricaded himself and nine hostages, including three infants, inside the maternity wing of a hospital. He released them unharmed about 17 hours later and was arrested.

Richard Worthington, a 39-year-old father of eight, was taken into custody unharmed after negotiating with authorities. Explosives were found in the maternity wing of Alta View Hospital and were being disarmed by federal agents, Police Chief Gary Leonard said.

The freed hostages were driven away in an ambulance. Several were hugging each other, and some wept. Hundreds of yards away, members of Worthington’s family did the same.

Worthington’s older brother, Allen, said he was relieved.

“I hoped it would end this way because I love my brother,” he said.

Leonard said Worthington had set conditions for his surrender, but the police chief did not reveal what they were.

Worthington began negotiating by telephone with police about 15 hours into the standoff, Leonard said. He reportedly told negotiators that he was carrying dynamite and “would blow the place up” if police rushed the building.

Police said Worthington held six adults and three infants on the top floor of a maternity wing that is connected to the main building by an enclosed sky-walk. Police said he allowed nurses to care for the infants.

Authorities did not say why Worthington went to the hospital, but Dr. Glade Curtis, an obstetrician who escaped from the maternity wing, said he had performed surgery to tie off the fallopian tubes of Worthington’s wife, Karen, two years ago. He said Worthington had threatened him repeatedly since the surgery.

Authorities declined to say whether Worthington had been trying to get to Curtis.

More than 70 officers cordoned off the area and evacuated residents for three blocks east of the building in this Salt Lake City suburb. Land to the west, north and south is vacant.

Dr. Brent Mabey, an Alta View emergency room physician who treated the victim, Karla Roth, 37, said a clerk ran into the hospital shortly after midnight to say a man with a shotgun had just blown out a window in the adjacent Women’s Health Center.

When police arrived, they found a woman who had been shot in the hospital’s parking lot, Mabey said.

“We got her on a stretcher and took her back into the emergency department. She did not survive,” Mabey said.

Worthington’s wife and the local Mormon bishop were at the scene but were kept from reporters.

Neighbors and friends described Worthington as a quiet man, something of a loner, with a strong work ethic and a love for his children.

“He took them everywhere, even when he went to work,” said Alice Whitemore, a longtime friend.

One neighbor said Worthington either owns or works for a landscaping business in Sandy.

Jess Gomez, a spokesman for Alta View Hospital, said the remaining 32 patients had been evacuated from the 75-bed hospital.
