Authorities say the first fugitive from Houston’s new “Top 10 Most Wanted Gang Fugitives” list has been captured in Mexico. Raul Sergio Madrigal is considered to have been a key narco player here before fleeing south of the border, where he’s believed to have been for a few years. He may have drawn additional attention by photos of his life on the run that were posted on a myspace page: Madrigal at the clubs in Mexico.
