Buckley's Death Still A Mystery After Preliminary Tests

June 17 [7:55 EDT] -- According to a preliminary toxicology report from the Memphis medical examiner's office, singer Jeff Buckley had no drugs or significant levels of alcohol in his system when he drowned in Memphis Harbor on May 29.

While the singer did have inconsequential trace amounts of alcohol in his system, it is not believed to be a factor in Buckley's death.

Buckley, who had been preparing to record his second album in Memphis, had been hanging out with a friend on the banks of the Mississippi. The singer decided to wade into the water fully clothed, and suddenly disappeared under the wake of a passing boat. His body was discovered in the harbor on June 4.

The final autopsy report on Buckley should be complete in another week, but sources in the medical examiner's office do not expect much more in the way of new information. A final ruling of death by accidental drowning is expected.
