Authorities are investigating the death of a Columbia man as a homicide.

The Columbia Missourian reports that police identified the victim Sunday as 25-year-old Edmond "Ricky" Randolph Jr. He was dead early Saturday when emergency responders rushed to an apartment in northeast Columbia after receiving a report that a man had gone into cardiac arrest.

Police Department spokeswoman Bryana Larimer says she didn't know who initially called police, but it wasn't Randolph.

The investigation is ongoing.
