Probers want Whitney Houston's medical records

NEWARK, N.J. -- Whitney Houston lived much of her life in public, but on Saturday, the singer's family and friends will remember her in private.

An intimate, invitation-only service is being planned at the 1,500-seat New Hope Baptist Church, where Houston first showcased her singing talents as a child.

"They have shared her for 30-something years with the city, with the state, with the world -- this is their time for their farewell," observes Carolyn Whigham, owner of the Whigham Funeral Home.

Houston died Saturday at the age of 48 in the Beverly Hilton. The investigation into her death continues. It's been reported she was discovered underwater in the bathtub of her hotel room. Police also found several prescription drugs in the room.

A determination of the cause of death is pending toxicology test results expected to take several weeks. In the meantime, investigators have requested all of Houston's medical records. They want to know why prescription drugs were inside her hotel room when she died. CBS Radio Correspondent Steve Futterman reports the coroner's office has subpoenaed records from Houston's doctors and pharmacies. The process began yesterday. The coroner emphasizes that this is strictly routine and done in countless other death investigations.
