Police sources say
none of the three women were cooperative with investigators. "

So 3 women - one of which is the 19 y.o. Someone else was quoted as saying a woman lives there with two teens, right? I think it is more likely that the older woman (in 50's) lives there with a 27 ('ish) y.o. who may look like a teen, and the 19 y.o. Then we think there was possibly other younger children in the home - they could either be the children of the 27 y.o. or nieces/nephews visiting. Just thinking out loud.
