At first I thought that Amanda was probably guilty but after considering all of the evidence I think this explanation is the most likely single explanation (i.e. not necessarily that the probability is high but that it is higher than any other detailed explanation.) It’s possible that she came in after Guede left but while Meredith was still dying, then she panicked and therefore behaved suspiciously and lied about her activities afterward.
