OMG, this doesn't explain someone using the computers on the evening of the 4th and the early morning of the 8th!!!!! Drop down search, google search, bookmarks, it doesn't mean anything, urgh.
Actually, IF they can prove the MS Family was killed on the 4th, the following days will also have to "jive" with their theory on the following days of their murder. Accessing their PC/Phone Records CAN nail down a timeline of ANYONE who was close to them, IMO. So far, it appears ol CM has some ????'s to answer, IMO.
