The idea itself is very cliched. Serial killers can be utilized very well (See: Alfred Hitchcock's Psycho, Cormac McCarthy's No Country for Old Men) but if the killer lacks a decent motivation, like in this micro, then it can make the story fall apart quickly and easily. Also, parts of it sort of make no sense; who was the woman at the top of the stairs? Was she a ghost? Or a housemate? I assume this would (and should) be explained in later parts but the fact that this is posted as only one chunk of a longer work it will just leave the reader scratching their head with a bewildered "huh?"

Like you said, I recommend putting all the parts into the final draft and posting it up here so it will clear up some confusion for the reader. I'll give a fuller review then.
