NBC 6's Tom Llamas was live in Little Havana as crowds celebrating Castro's alleged death continued to grow.

A large group of Cuban-Americans went to Versailles, the town square in Little Havana, to find out if Castro was alive or dead.

Llamas said the group arrived just before 10 p.m., waving flags and screaming. He said it was only a fraction of what will happen when Castro's death is finally confirmed.

The rumors began on July 31, 2006, when Cuba TV announced Castro had transferred power to his brother, Raul.

Castro cited intestinal problems as the reason he could no longer run day-to-day operations in the country.

Medical experts in the U.S. said Castro only had a year to live.

Now, that year has come and gone, and many Cuban-Americans suspect the dictator has died.

"It's been crazy," Carlos Vega said. "Everywhere you go, that's all they talk about. Radio stations, everywhere. Everybody's going nuts."

Rumors in the media, on the Internet and on the street say Castro is dead.

"Somebody that I work with, their husband's in Hialeah, out of all places," Lazaro Quintino said. "They gave him a call when the rumors were starting to go around. The funny thing is, just minutes after that, my wife gave me a call."

Quintino said his cell phone started ringing off the hook around 1 p.m. Friday. Quintino said they were all asking the same question: Is Castro really dead?

"A friend of the family that knows somebody that works for the government told them that Fidel had passed or that he was almost about to go," Quintino said.

One woman said she heard there were tanks seen in Cuba and funeral "people" had arrived in Cuba from Russia and Egypt.
