An autopsy failed to determine what killed a Los Angeles County employee who was found dead in an office cubicle.

Rebecca Wells, 51, collapsed at her desk at the Department of Internal Services in Downey. She was last seen alive Feb. 11, but it wasn't until the next afternoon that anyone realized she was dead.

Her body was finally discovered by a security guard. Officials are now waiting for the results of a drug test.
