In the end, a TV show helped accomplish in five days what investigators had not been able to do in 14 years: locate the man suspected of detonating the bomb that killed a Chilean dissident.

On Tuesday, Virgilio Pablo Paz Romero was arrested as he pulled up in his pickup truck to the landscaping business he has operated for six years near West Palm Beach, Fla.The Cuban exile was the remaining fugitive in the Sept. 21, 1976, Washington, D.C., deaths of former Ambassador Orlando Letelier and aide Ronni Moffitt.

The arrest came after someone watching Fox-TV's "America's Most Wanted" on April 19 recognized Paz's picture as the face of landscaper Frank Baez.

Paz, 39, was arrested on charges of conspiracy to murder a foreign official and conspiracy to manufacture explosives.

He has been held pending a bond hearing. On Friday, a federal magistrate in West Palm Beach decided to move the hearing to Washington.

"For us, this is a big capture," said John Walsh, host of the 3-year-old series based in the nation's capital.

Of 347 fugitives profiled on the Fox show, 148 have been arrested as the direct result of viewer tips.
