The lawyer for an American who fled Colorado and started a new life in Argentina says his client is being politically persecuted and is appealing for asylum in hopes of avoiding extradition to the U.S. to face murder charges.

The Argentine Supreme Court ruled last month that Kurt Sonnenfeld, who moved to Argentina in 2003 after being charged with killing his wife, could be extradited.

Sonnenfeld claims his wife killed herself and that prosecutors framed him for her death to silence him, allegations that Denver's district attorney's office has denied. Sonnenfeld had been a cameraman for the Federal Emergency Management Agency at the World Trade Center after the Sept. 11, 2001, terrorist attacks and claimed to possess video footage indicating the government knew the attacks would happen.
