At least one caller offered a theory about a relative who might have done Whitney Houston in, but offered no supporting proof.

The Los Angeles Coroner’s Office has not verified the callers were indeed relatives.

The Coroner has already said there was no sign of foul play or trauma, but the official cause of death won’t be determined until toxicology results are in.
