They both started a new happy chapter of their lives. Bought a house in May, 2020,
married there January, 2021. They were parents of a 1 and 4 year old. Spencer had a relatively young career that was emerging, This was a relatively new positive chapter of their life. Their 5 year anniversary was just coming up and according to Rob Misleh they were going to celebrate it.

Now, the personal interviews the police have with their friend circle/family could be holding a key piece of info in this regard (was someone having an affair, was thre any threats or people with perceived slights or odd interactions with a repair man, or local etc. etc.). We are here sleuthing but, sure, it's very hard with an incomplete picture and there's always the real possibility of a statistically rare out of the blue exotic scenario.
