EDMUNDSON, Mo. (AP) — Police suspect a woman died from complications after receiving illegal, cosmetic injections in her buttocks at a hotel room in the St. Louis suburb of Edmundson.

Edmundson Police Chief Miklos Hurocy says officers investigating 22-year-old Daysha Phillips’s death last week are awaiting the medical examiner’s report. Hurocy says he’s “pretty confident” the medical examiner will rule the case a homicide.

Phillips died July 30 when she was taken off of life support at a hospital.

Hurocy says friends of the Florissant woman had taken her to the hospital four days earlier after she had difficulty breathing following the procedure.

Police are trying to identify the person who gave the injections.
