There is no evidence that any foul play was at work in the death of Whitney Houston.
But that did not stop Nancy Grace from speculating about whether someone played a role in her passing, and a new report claims it isn't stopping unidentified callers from pressing the Los Angeles County Coroner's Office from opening up a murder investigation.
Sources tell TMZ that several individuals - alleging to be relatives of either Houston or Bobby Brown - have contacted the office under the belief that the artist was murdered. One even claimed to possess evidence that proved this theory, while another blamed a fellow relative for the homicide.
There's been no verification of identities and still no proof exists that points to anything but an overdose on pain medication and alcohol. The official cause of death will be determined when toxicology results are in.
