Well, that makes me wonder if there will be anymore material witnesses. I suppose the staff at the Y and the sheriff's deputy might be called by the defence, but from what's been said I don't know if that would help GR very much - I think it was stated the Y staff themselves tipped off LE that GR had visited outside of his usual time, and made a big fuss about Jennifer going shopping?
I wonder what impression the deputy got? I don't recall any information or quotes about that exchange. I'm thinking if GR was trying to make people pay attention to his presence, and being over-friendly, it may have made the deputy a little uneasy and what was said would have stuck in his mind.
It's my understanding that the material witnesses are called by the State; therefore, any testimony would be more likely to support the murder indictment. Material witnesses could include anyone he spoke to or who saw him on the day of Jennifer's murder -- school personnel or other parents (when dropping off kids), YMCA staff and anyone else who spoke to him at the Y or observed his demeanor, ES, of course, as she gave him a ride home that day, Jennifer's parents (he called them that evening), and the officer who took the missing person report. Maybe the children? (not sure about the law on that). Maybe any colleagues from IBM with whom he would have communicated that day (although I doubt he had time for much conferencing). Also, anyone who had pertinent conversations with GR in the weeks preceeding and months after her murder (i.e. saying he wanted to spend the rest of his life with ES).
If I understand correctly, material witnesses could be called to verify his whereabouts on the day of the murder, whether his alibi holds any water, any converations that might be significant, his appearance and demeanor on the day of Jen's murder, etc. If children are permitted to testify, they can attest to whether or not they saw their mother alive that morning, whether she was up and dressed or still in bed, whether she was alert or seemed unusually...sleepy/disoriented. Material witnesses may also be called to report if something were missing that GR could have access to -- such as a bottle of benzodiazepine.
Material witnesses could also be called to give testimony of any knowlege they might have as to whether Jennifer was physically abused in the months/years leading up to her murder. If, say, friends, employer, relatives saw marks on her arms, or if they observed her being treated roughly, or if she confided in someone to that effect. Also, since she'd made an appointment with a divorce attorney -- anyone she may have confided in regarding that and her reasons for seeking divorce.
