It's been confirmed by Tomm Hulett on Silent Hill Heaven's facebook page that none of the monsters in Downpour have anything to do with Murphy Pendleton. They are all manifestations of Anne. When asked about how the monsters could be hers, Tomm replied "Maybe she's afraid of people". He then said, "Dolls are loss of innocence". He went on to say, "Every monster has a potential Murphy meaning amd an Anne meaning. Murphy is a "wrong place" character who can be redeemed. Anne is the typical damned SH protag who must either be redeemed through Murphy (her Mary) or murdered - which damns Murphy".
