They were kidnappers, drug dealers, extortionists who the CJNG executed in their cleanup of the city.

Here's a (poor) translation from the article:

Several sources have mentioned that the capital will suffer a kind of clean as in the time of The Michoacan Family, when they did not allow bums, bad living and drug addicts to get together in the corners, in addition to start executing them in case of ignoring the Signs of the cartel, also thieves will suffer the same consequences as the people of the video.
