Police are investigating a man who showed up at a police station on Thursday and confessed to brutally killing his 26-year-old wife and posting a picture of her lifeless body on Facebook.

Jennifer Alonzo was found dead inside the couple’s home after Derek Medina, 31, showed up at the station and said he killed his wife during an argument, a local NBC affiliate reported.

Miami-Dade police are currently investigating the case, but no other information was made immediately available.
