Horrified onlookers called Michoacán State Police after spotting the suspect, identified only as Sebastián, holding his 26-year-old sister Julieta’s head near a clinic in Quiroga on Saturday, local news outlet AM reported.

Officers arrested the apparently intoxicated man without incident and confiscated the rifle he was carrying, according to the report, which cited the state prosecutor’s office.

They found his sister’s naked corpse lying at a gas station several hundred feet away.

Authorities were investigating a possible motive for the gruesome crime.

No information was immediately available about what charges the suspect faces while he is being held by the Michoacán state prosecutor’s office.

The alleged feminicide was reminiscent of another incident in Mexico in which Lev Norman was arrested for allegedly carrying the head of Lucero Yazmin Hidalgo in a backpack in October 2022.
