Beverly Hills Police Close Investigation Into Whitney Houston's Death

LOS ANGELES (CBS) — The Los Angeles County Coroner's Office released their final report Wednesday on the death of Whitney Houston.

The Coroner's Office concluded that the death was an "Accident" and they listed the official cause of death as "Drowning," according to a statement from Lieutenant Mark Rosen.

"The Beverly Hills Police Department has conducted a formal investigation and found no evidence of foul play," the statement said.  "Based on the findings of our investigation and our review of the Coroner's Report we have determined that this is not a criminal matter.  The BHPD investigation has been officially closed. Our condolences go out to her family, friends and fans who mourn her untimely passing."

The official autopsy report was released last week, detailing additional information about the Houston's death.

Houston, 48, was found submerged in a bathtub filled with extremely hot water (93.5 degrees) in her Beverly Hilton hotel room on Feb. 11, the day before the Grammy Awards.

Cocaine, marijuana, Xanax, muscle relaxers and allergy medications were all found in Houston's system when she died, according to the final report from the Coroner's office.

The coroner previously confirmed that prescription pill bottles were found in her room, but "not in alarming amounts," according to People.com.

According to the final autopsy report, "a small spoon with a white crystal-like substance in it and a rolled up piece of white paper," were found in the room by Los Angeles police detectives.

The spoon tested positive for cocaine, according to TMZ. Remnants of a white powdery substance were also found on a small mirror, the report said.

Loose tablets of prescription drugs were also found around the room, prescribed by at least four different doctors, the report noted.

No trauma or foul play was suspected.

Houston reportedly ingested cocaine just before she slipped under the water, according to the findings.

The report says alcohol did not play a factor in Houston's death.

The report stated that Houston was last seen alive between 2:45 and 3 p.m. on Feb. 11 by her personal assistant. The singer had complained of a sore throat and her assistant recommended that she take a bath prior to pre-Grammy party.

When the assistant returned to Houston's room approximately 40 minutes later, she found the singer face down in the bathtub.

Houston's assistant and bodyguard called 911 and pulled her body from the bathtub at 3:43 p.m. She was later declared dead at 3:55 p.m. by paramedics, the report said.

Houston had a long history of substance abuse problems. She and then-husband Bobby Brown were arrested in 2000 at a Hawaii airport with marijuana.

The singer was last in rehab in May 2011, but was reportedly seen in the days before her death acting erratically.

Houston was laid to rest on Feb. 19 in New Jersey.
