 Despite these official conclusions, the chief investigator for the Cook County Coroner's Office, Harry Glos, disagreed with the official time of death, later stating to the media there had been numerous "marks of violence on those girls' faces" strongly indicative of their being the recipients of violence as opposed to postmortem rodent infestation.Glos also contended that a thin layer of ice found encrusted upon the sisters' bodies indicated they had most likely been alive until at least January 7, since only after that date would there have been sufficient snowfall to react with the girls' natural body heat in such a climate and thus create the layer of ice discovered upon their nude bodies in this location.Glos contended this proved their bodies had been warm when their bodies had been deposited beside German Church Road, since only after January 7 had there been sufficient snow to create such an ice layer upon and around their bodies.
