Juli McDonald from WBZ (tv station in Boston area) reported that "They hosted friends for NYE." Her mother was told by her son-in-law "not to worry about her missing daughter" (reported above from report in kurir). Whether he killed her or not, I have no idea. If not, maybe one of the friends whom they hosted on NYE left with her in their car. She could have been an Eastern European spy (she reportedly had very refined language skills - her English having only a very slight accent) and the time was for her to "return to base" before getting further legally entangled in any of the shenanigans for which her husband has been convicted. The mother in law may in fact have seen her leaving with suitcases, but it might have been with one of their guests at what was actually an earlier hour than she thought, and it would have been due to a "work emergency" even if not one with the property management firm for which she worked.
