Hi momtective.
Adoptive mom's name is C. Priem. (Christina AKA Tina)
We haven't determined who C. Newton is, they were named as a "friend" on the adoptive mom's myspace. (we might need to go back and take her name off thread).
Syler was seen at camp (from sheriff presser) by independent eye witness(es) who were unnamed in media that said they saw Sylar at campground as late as 9:30 PM the evening prior to his being reported missing. (noticed missing at 1:45 AM, 911 call came into center at 2:30 AM and LE on scene by 3 AM, all from links backthread).
HTH.
