ST. LOUIS – A 63-year-old St. Louis woman died less than a month after having hot oil dumped on her.

According to a spokesperson for the St. Louis Metropolitan Police Department, the attack happened just after midnight on March 7 at an assisted-living facility in the 5400 block of Thekla Avenue, located in the Walnut Park East neighborhood.

The victim, identified as Doren Davis, was rushed to a local hospital to be treated for severe burns. Officers learned Davis and her alleged assailant were roommates.

Davis died of her injuries on April 3. The St. Louis Medical Examiner’s Office ruled the manner of death as a homicide.

The roommate was arrested the day of the attack and remains in custody with the Missouri Department of Corrections.
