It's been covered many times in these threads - and is in the early media threads. From memory, what happens is that the daughters call BM, who calls the neighbor. Neighbors goes to check and gets back to BM. BM tells her to call 911 so she does.
We now know that the neighbor probably went into the house. We don't know how many phone calls (no way of knowing that). We do not know exactly what BM said, except for the neighbor's early account (which is lacking in detail).
She never mentions feeling "forced" (I'm not sure how anyone could know, except her and she hasn't used those words). She was being neighborly.
She has never mentioned that she thought "something else was up."
We don't know when the calls from the daughters started. We know that by around 6 pm, LE was called and arrive on scene well before Barry, and discover the bike (and BM, meantime, has asked a friend of his to go over and see what's up). Barry arrives sometime after 9 pm.
The police do not let him back in the house. If the neighbor was able to get into the house, as I believe, she may well have offered access to LE who, after all, have been called for a welfare check.
Police impound his truck, etc. Then about 2 weeks later, he's allowed back into the house (and gets his truck back?)
