Houston's body arrived at the Los Angeles County Coroner's Office in the Boyle Heights area of LA 11 hours after she was declared dead at the Beverly Hilton Hotel, reports CBS2 in Los Angeles.
The pop superstar was pronounced dead 3:55 p.m. Saturday in her fourth-floor room at the Beverly Hilton Hotel.
Kirk Hawkins, reporting for CBS2 and KCAL9, said paramedics performed CPR for 20 minutes prior to that after they were called by a member of Houston's entourage.
Houston was found unresponsive in a bathtub in her fourth floor hotel room.
Houston's family says they talked to her earlier Saturday and didn't believe anything was unusual.
But during a rehearsal last week, some witnesses said she was sweating profusely while others said she was doing handstands by the pool at the hotel.
Coroner's officials say they can't talk discuss what they saw in her room.
"It didn't appear that there was foul play and that's all I can say about it," said Los Angeles County Asst. Chief Coroner Ed Winter.
Toxicology tests will determine if legal or even illegal drugs played a role in her death. The results of those tests could take several weeks.
However, an autopsy is expected begin at some point Sunday.
