HONOLULU -- The FBI is investigating alleged government corruption in tsunami-ravaged American Samoa, according to a CNN report shows millions of your taxpayer dollars that were supposed to create a tsunami warning system went missing.

The earthquake and tsunamis in American Samoa left 34 people dead last month. A CNN investigation shows lives could have been saved. (Read CNN's report.)

Documents show U.S. taxpayers shelled out nearly $13 million in disaster preparedness grants since 2003, including construction of a tsunami warning system.

Samoa's former homeland security advisor, who was fired two years ago, said he was working on a plan for warning sirens, but claims some money went missing to pay for extra government jobs.

Government reports also show some money paid for travel and entertainment charges in Las Vegas, flat screen TVs and expensive leather chairs.

American Samoa's governor said there was a disaster study, but no plan for a warning system.

"I was trying to get verification of what happened to that application, but I wasn't able to get the definite information," Gov. Togioloa Tulafono said.

Tenari Ma'afala leads the Honolulu police union and lost two family members in American Samoa. He said that if the report is true, he is "angered and embarrassed for the Samoan community."

Evonne Andrews, whose aunt drowned in the tsunamis, said government officials were greedy.

"It's messed up what they did with the money," Andrews said.

Gus Hannemann, a former American Samoa legislative member in Hawaii, said he believes funds were not misused and that no government officials personally profited from American taxpayer dollars.

"I don't want the Samoan people here to be embarrassed by this. No one gained from it," Hannemann said. "The fact is that they froze the funds and the responsibility should have been on the federal government."

CNN has learned the U.S. government froze those federal grants in American Samoa.
