Updated at 3:01 p.m. ETAt least eight people have died at a Florida nursing home that was left without power — and reportedly without air conditioning — in the aftermath of Hurricane Irma, and police have launched a criminal investigation into the incident.Three people were dead when authorities arrived at The Rehabilitation Center at Hollywood Hills, Tomas Sanchez, police chief in Hollywood, Fla., told reporters Wednesday."The suspicion is that these deaths should not have occurred," NPR's Jon Hamilton reports from the scene.Sanchez declined to say exactly how hot it was in the building when authorities arrived, simply saying: "I can tell you it was very hot on the second floor." He also would not state exactly how long the building was without power, saying it was part of the criminal investigation.A kitchen worker at the center told the Miami Herald that the facility "had power from a generator to cook meals, but no air conditioning."More than 100 residents were evacuated from the facility, Broward County Deputy Fire Rescue Chief Tim Keefe said at a news conference earlier Wednesday. Some were from facilities nearby.When asked about whether police responded quickly enough to a distress call, Sanchez said that there is dispute about when exactly the call came in, though he estimated that it was about 6 a.m. ET. He added that the initial call was about a heart attack and that rescue workers began evacuating patients between 7:15 and 7:30 a.m.Randy Katz, medical director of emergency services at the nearby Memorial Regional Hospital, said that when hospital officials heard about the situation, "we mobilized at least 50 to 100 of our employees that left the hospital, ran down the street, pulled all of these patients out of the facility and made sure they got to a safe place."He added that the patients who have been admitted to the hospital are mostly being treated for "respiratory distress, dehydration, and heat-related issues."According to the Herald:
