Canadian real estate developer Adam Anhang was the target of a $3 million plot in which wife Aurea Vazquez Rijos tried to kill him, according to reports.
Vazquez was arrested Sunday by police in Spain after being sought for five years in the alleged murder-for-hire scheme in Puerto Rico, the FBI confirms.
The Puerto Rican suspect was taken into custody as she got a flight from Italy, where she has lived for years and gave birth to another man's twins.
A U.S. grand jury charged Vazquez in 2008 with offering a man $3 million to kill her husband, and she has evaded attempts to bring her in since.
She denied the charges but refused to cooperate with police and fled Puerto Rico for Italy, where she lived in Florence and, more recently, Venice.
