Investigators also found five bags that may contain human remains, according to the Jalisco State Attorney's Office in a press release posted on Twitter
account late Saturday.
The remains were found in El Salto, a city southeast of Guadalajara, according to the prosecution.
The bodies and bags will undergo forensic analysis, the office said.
The state has seen increasing violence in recent years. It is the base of Jalisco New Generation, one of Mexico's "most powerful and fastest growing" drug cartels, according to U.S. Drug Enforcement Agency
. It split from the Sinaloa cartel 10 years ago.
The agency said staff continue to work "despite the health risk due to Covid-19" in basic areas, including in the search for missing persons.
