Three people were found dead on Balboa Island, Newport Beach police said Monday morning.
Police later confirmed drugs were found in the home.
Officers had responded to a medical aid call in the 100 block of Diamond Avenue just after 8 a.m. Monday and found three people dead.
Two women and one man were discovered dead while a second man was taken to the hospital.
Details on his condition weren’t immediately available.
Police would not release details on the victims’ names or ages.
Police were working to get a search warrant to go back inside the home, but they will do so only after a Hazmat team deems the rental unit safe.
The unit sits above a garage in the alley behind Diamond Street just a few steps from the Bayfront. It's a tightly packed neighborhood of vacation rentals and homes often passed down from one generation to another.
Police are not convinced they’ve found everyone connected to what appears to be an overdose. They're asking for witnesses to come forward.
