Just to clarify, though:
Joe was the boyfriend (arrested first)
Dave Newbeck (arrested in Houston) was the guy with the girlfriend, Jen, who people were saying was really responsible.
Jen, if I recall correctly, was accused (on the boards, so rumor) of stealing Mandy's identity, while working for the Suffolk County DA. Has she, too, been arrested?
Are all the all parties that people speculated were involved in custody now, except the girlfriend? I wonder if they were running all this time, or just went missing recently when the heat got turned up?
