Death toll rises in Florida nursing home affected by Hurricane Irma
A 12th death has been reported from a US nursing home that lost its air conditioning during Hurricane Irma.
The Broward County medical examiner's office in Florida confirmed the death of 57-year-old patient Dolores Biamonte on Friday.
Officials said she died on Thursday night.
Hollywood, Florida police spokeswoman Miranda Grossman said her department is treating all deaths from the Rehabilitation Centre at Hollywood Hills as part its criminal investigation.
Eight patients died on September 13, three days after the storm knocked out the nursing home's air conditioning.
Others died in the following days.
Some who died had body temperatures as high as 48C (109.9F).
Investigators want to know why the patients died after the storm even though a fully functioning hospital sits just across the street from the nursing home.
