Mexican authorities have said that human remains found in bags in a ravine in the western state of Jalisco last week are those of eight call centre employees who had been reported missing.
The discovery was made last week at the bottom of a 40m ravine in the municipality of Zapopan, a suburb of Guadalajara, a large industrial hub.
The authorities had launched a search for two women and six men, all aged around 30, who had been reported missing since around 20 May.
Forensic evidence "confirms that (the remains) correspond to the young people who ... had been reported missing," the Jalisco state government said in a statement.
Authorities did not indicate how the victims may have died.
The missing person reports for each one of the employees had been made separately on different days, but investigators found that they all worked at the same call centre.
Initial inquiries suggested the call centre could have been involved in illegal activities.
Relatives of the missing have criticised authorities, saying they had been to slow to find their loved ones and to investigate the call centre.
In recent years, human remains have been found in bags or unmarked graves in different areas of Jalisco.
The Jalisco New Generation cartel operates in the state and is one of the most powerful organised crime groups in Mexico.
It is involved in disputes with other drug syndicates.
Mexico has recorded more than 340,000 murders and some 100,000 disappearances, the majority attributed to criminal organisations, since the launch of a controversial military anti-drug offensive in December 2006.
