Police found corpses belonging to 44 people in a mass grave on the outskirts of a Mexican city.
Local residents began complaining about the smell from a nearby well and police were called to investigate.
The well in Jalisco state was dug up and the remains were found stuffed into 119 black bags.
Jalisco is the heartland of one of Mexico's most violent drug gangs and this is the second major find of bodies in the state this year.
According to the BBC, most of the bodies were cut up so authorities had to piece together different parts in order to identify them.
A local organisation which searches for missing people has appealed to the government to send more specialists to assist with identification.
They say the local forensic department is overwhelmed and does not have the necessary skills to complete the operation.
For several days there was “a plague of flies" around the well and the smell became unbearable after the September rains.
Local media report that spokesman for the local authorities said "many of those we have found in the graves have a criminal record".
The site is 35 minutes drive from Guadalajara, the capital of Jalisco state, a city where so far this year more than 15 burial sites, some holding dozens of bodies, have been discovered.
Last month, Jalisco New Generation Cartel(CJNG) drug cartel, which is among Mexico’s most powerful, released shocking footage of a rival gangster being interrogated and then slaughtered.
In the video, a group of ten alleged gang members wearing military-style combat gear and armed with rifles surround a captured man from a rival drug gang.
According to local media reports, the half-naked man is said to be Aldolfo Mendoza Valencia, aka ‘El Michoacano’, who is one of the leaders of a rival gang the Santa Rosa de Lima cartel in the Valle de Santiago.
