A man was found dead early Thursday morning in a home on West 12th Street in the city’s Durkeeville neighborhood, the Jacksonville Sheriff’s Office said.

Police said officers were called to the home just west of Myrtle Avenue North at 3 a.m. on reports of “an altercation with injuries.”

The police found the man dead inside the home, and a woman was detained at the scene. Investigators said she was the person who called 911.

Police did not say if the man had injuries or how he might have died.

Because the circumstances of his death and the relationships of those involved are not yet known, the case is being classified, JSO said.

Investigators are working with the Medical Examiner’s Office and the State Attorney’s Office and are asking anyone with information about the incident to contact JSO at 904-630-0500, email [email protected] or call CrimeStoppers at 1-866-845 – TIPS.
