The Medical Board of California acknowledged Thursday that it is investigating a Los Angeles doctor who, according to documents, authorized all 11 prescription medications found in Anna Nicole Smith's hotel room the day the starlet died of a drug overdose.

Dr. Khristine Eroshevich, a Los Angeles psychiatrist and friend of the former Playboy Playmate, is under investigation, board spokeswoman Candis Cohen said.

Cohen declined to provide other details.

On Wednesday, Cohen would not comment on a possible investigation, saying such information was not public record.

Repeated calls to Eroshevich on Wednesday and Thursday were not returned.

According to documents from the medical examiner's office in Florida, Eroshevich authorized all the prescription medications in the Florida hotel room where Smith was found unresponsive shortly before her death on Feb. 8.

Eroshevich had traveled with Smith to Florida.

More than 600 pills, including 450 muscle relaxants, were missing from prescriptions that were no more than five weeks old, according to the documents, which were obtained by The Associated Press through a public records request.
