Whitney Houston death certificate: No cause of death listed

(CBS/AP) The official cause of Whitney Houston's death is still a mystery, and that fact is reflected in the singer's death certificate.

The document was filed Wednesday with the Los Angeles County Department of Health in California. It does not list a cause of death.

It lists the manner of death as "pending investigation," with the immediate cause of death listed as "deferred."

What the certificate does reveal is that Houston will be buried on Saturday at Fair View Cemetery in Westfield, N.J. - the same location where her father, John Russell Houston Jr., was laid to rest in 2003.

The document lists her occupation as "Entertainer," and says she worked as one for 33 years.

Houston was found dead in her Beverly Hills hotel room on Saturday, at the age of 48. Her funeral will be held at the New Hope Baptist Church in Newark, N.J., the same church where she sang as a child. Fans will be able to watch the private service online.
