Authorities are asking for the public's help in the mysterious death of an Oklahoma woman.

Cleveland County Sheriff Joe Lester said Thursday that detectives are trying to locate a potential witness in the death of Rebecca English.

English was found dead at her rural Norman home April 28.

Detectives have learned she was with several people in the area of Thunderbird Casino and the Country Palace Saloon before she died.

The state Medical Examiner's office hasn't listed a cause of death.

The witness is a white woman in her late 20s named "Andrea" or "Andi." She may have star-shaped tattoos on her forearms and may work in the home health care industry.

Anyone who has information can call (405) 321-8600.
