After days of probing still many questions remain in the death of R&B singer Vesta Williams. Results of her autopsy did not provide enough details to determine whether the 48 year old died of an accidental overdose or suicide.

Williams was found dead in a Los Angeles hotel room on Thursday [September 22]. Investigators found bottles of prescription pills at the scene. While foul play was ruled out, sources told TMZ that the cause of death is undetermined pending toxicology reports, which will be available in 4-6 weeks.
