Double-Murder Suspect Is Former Russian Special Ops Soldier, Will Likely Elude Extradition

Nikolai Rossi, the main suspect in the brutal double-murder in which a mother and daughter were stabbed to death--was a Russian special ops solidier, according to acquaintances who talked to The New York Post and The Daily News.

Rossi boarded a jet to Russia hours after Tatyana and Larisa Prikhodko were murdered. He will probably elude extradition back to the United States to face trial for the brutal stabbing murders of the two women.

From The Daily News:

A friend of the fugitive double-murder suspect said Tuesday that Rakossi was an elusive target who did tours in Vietnam, Afghanistan and Africa.

"If he doesn't want to be found, he will never be found," said Rustam Zaripon, manager of the Russian Baths in Sheepshead Bay. "As far as soldiers go, he was the elite of the elite. He's gone."

Further complicating the investigation is the lack of an extradition treaty between Russia and the US. Yevgeniy Khorishko, spokesman for the Russian Embassy in Washington, told The New York Post, "According to the Russian constitution, Russian citizens can't be extradited to [a] foreign country."

Rossi took a cab the morning after the murders to JFK airport, telling the driver he was going to Kaluga, a city 60 miles outside Moscow, because his wife was ill. He had scratches on his face and a bandaged nose, the driver told The News.

Tatyana and Larisa Prikhodko were both nurses. There is a memorial at the building where they both lived in separate apartments, according to ABC News.
