At the end of June, 2003, NBC news requested David Mariasy of Team Audio to enhance and analyze parts of the 911 call from the JonBenét Ramsey murder case.
Many theories have been made as to what happened to JonBenét. One of these theories involves what was actually said during the inaudible parts at the end of the original 911 call.
NBC aired their report on the analysis of the 911 tape by audio experts on July 9th, 2003, which names David Mariasy as one of their experts.
Mr. Mariasy’s conclusion was that the alleged voices of three people engaged in dialog at the end of the 911 call was not substantiated.
This tragic case has been documented intensely, for more information on the 911 call please see the JonBenét Ramsey Case Encyclopedia.
