Authorities in Colombia have arrested a woman they say set up businesses to launder money for Mexico's most-wanted man, Joaquin “Shorty” Guzman.

Officials Wednesday announced the arrest of Dolly Cifuentes Villa, alias “La Meno.” She was taken into custody earlier this week in the city of Medellin.

Investigators say Villa was responsible for several illegal businesses in Colombia and outside the country that were put to use by Guzman. They also say she is the sister of Francisco Cifuentes Villa, who officials say once worked as Guzman's pilot.

Guzman is head of Mexico's Sinaloa drug cartel and is that country's most-wanted man. He has been on the run since escaping from a Mexican prison 10 years ago. The United States has offered a $5 million reward for information leading to his capture.

Guzman is one of the world's most powerful drug traffickers and richest men. The U.S. financial magazine, Forbes, estimates he has a fortune of $1 billion.
