I wonder if he turned up at the house and took one of the victims at gunpoint and forced them all to get in the two vehicles in a “get in and you (second car) follow me or I’ll shoot [victim].
As for why the baby was spared (thank god, tho so cruel to wipe out her whole immediate family.. the mum and dad look so so young and happy in their pictures. They’re ALL so young.. a 15 year old kid.. and the grandma who is a year younger than me who doesn’t even have kids yet! So many long lives that should have been lived

)
Many brutal murderers, as heinous as they are, still have personal lines that are too far even for them. Brian Grossburger murdering all four of those vibrant, innocent kids in cold blood while they slept/just woke up, but sparing Murphy the dog springs to mind in recent memory. As previously mentioned she is also too young to have “seen his face and have to go” so to speak.
Of course there are far far to many evil murderers where nothing is too far for them (9-months-pregnant Savannah Soto whose partner was the target! little Bella and Celeste Watts by their own “father”, elderly Stephanie and Daniel Menard, and their dog Cuddles (over Daniel buying the killer a hot dog!j and countless too many more)
Whatever the reason, she is alive, in the silver lining of a very very dark cloud. RIP Braydon, Adrianna, James, and Cortney. And hope the suspect is caught soon.. and either fries or is sent to a far less lax prison for a lifetime of decidedly less luxurious incarceration than before.
MOO
