The boyfriend thing still has me so puzzled. How does it take so long to realize some one is missing? If he knew she was trying to collect the rent from the 2 POI's, and she didn't return, why does he not wonder where she and his unborn baby is for 5 days?
My spouse & I worked opposite shifts, but there were always signs of the other's activity. I would know if my spouse was there or not by simply looking around. Toilet seat up or down, anything new in the garbage, socks, undies, dirty clothes in the hamper / laundry, dirty dishes, shoes, coat, boots missing or present, foot prints in snow, vehicle tracks, food items consumed from the fridge, water droplets in sinks, shower, & tub, damp or dry towels, bed made or not, etc.
Maybe because I grew up in the home of a detective, I immediately see these things on arriving home. I would be would have at least started contacting relatives & friends within hours of her leaving based on observations made around the house showing lack of activity. It wouldn't take me 5 days to start wondering the where abouts of a family member. Especially some one carrying my baby. Even if he wasn't 100% sure that the baby was on it's way, from a home pregnancy test, he would have been fairly sure. We all know the home tests are pretty reliable, they've come a long way. He must have also known she kept close daily contact with her family members, I would think he would have been calling or texting them by night fall if she had not returned.
Like that TV show, the 1st 48 hours are the most critical. After that witnesses become unclear on details, evidence gets tainted, etc.
I also wonder if he asked his parents to come to Halifax or they just decided to come to support their son? Is the bf a person of interest as well? Did he ever reply to the request for her mother's name? Or was that the point he became suspicious?
