Spanish police have arrested a woman after five years on the run

A woman accused of hiring someone to kill her wealthy Canadian husband on the U.S. Caribbean island of Puerto Rico was arrested Sunday by police in Spain after being sought for five years in the alleged murder-for-hire scheme, according to the FBI.

The Puerto Rican suspect was taken into custody as she was getting off a flight from Italy at Madrid’s Barajas airport.

Aurea Vazquez Rijos was charged by a U.S. grand jury in 2008 with offering a man $3 million to kill her husband, real estate developer Adam Anhang. Anhang, 32, was beaten and stabbed to death in a popular tourist district of the Puerto Rican capital in September 2005 as he walked with Vazquez. He was killed as the couple walked from a restaurant he had bought for her in historic Old San Juan where they discussed their pending divorce. She sustained minor injuries in the attack

A Puerto Rican man spent eight months in a maximum security prison after being wrongfully convicted for the high-profile killing of Anhang before getting released in June 2008 after another man, Alex Pabon Colon, was indicted for the murder.

Since then, the FBI has been working to arrest Vazquez but ran into difficulties since Italy does not extradite suspects who face the death penalty.

She has denied the charges but refused to cooperate with investigators and fled Puerto Rico for Italy, where she lived in Florence and more recently Venice and gave birth to another man’s twins.

The FBI said the extradition process from Spain could take between six and nine months.
