BOGOTA, Colombia (AP)-- Authorities in Colombia say the sister of a man who founded the country's Northern Valley drug cartel has been killed by gunmen.
Luis Alberto Cantillo of Colombia's National Police says Lorena Henao was shot to death Thursday on a ranch on the outskirts of Armenia, a city in northeastern Colombia.
He says four suspects have been arrested in connection with the attack.
Henao's brother Orlando was one of the founders of the Northern Valley cartel before his assassination in 1998. She was married to Ivan Urdinola, who later became leader of the cartel.
The Northern Valley cartel rose to prominence during the 1990s, after the Cali Cartel and the Medellin Cartel broke up.
