Timeline from between 4am and 4:20am as detailed in PCA.
Approx 4am: XK collects DoorDash order.
Approx 4am: DM hears what she believes to be KG playing with her dog on the 3rd floor.
A short time later: DM hears someone she thinks is KG saying like 'There's someone here.' DM opens her bedroom door, looks out and does not see anyone. LE indicates this may have been XK as her phone indicates she was awake and using TikTok on her phone at 4:12am.
Unspecified time: DM hears what she believes to be crying coming from XK's room, DM opens her door for a second time and hears a male voice say something to the effect of, 'it's okay, I'm going to help you.'
4:17am: Dog is heard barking on a security camera. Camera also picks up audio sounds of voices or a whimper followed by a loud thud.
Unspecified time: DM opens her door for a third time and sees a figure clad in black clothing and a mask covering their mouth and nose walking towards her, the male walked past DM and towards the sliding doors.
4:20am: Suspect vehicle seen departing area of King Road residence at a high speed.
My opinion on the timeline is that XK stopped using TikTok when she made the statement 'there is someone here' around 04:12am. DM said she thought KG made that statement but LE included that it may have been XK, I think LE included this detail because the LE timeline may indicate that XK and EC were killed first.
Between 04:12 and 04:17 BK murders XK and EC.
At 04:17 BK goes to the third floor, hence the dog barking and kills MM and KG.
Tight to be in the car and speeding away at 04:20 but the only other thing I could think is, the murders upstairs were done at 04:17 and BK lifted the dog and threw it into a room, causing the whimper, thud and subsequent barking? (A point to add, not all vegans are animal lovers, some hate animals and hate the thought of eating from them, I believe one of the more infamous school shooters fitted that criteria.)
I wondered if perhaps XK had to walk round the front of the house to collect the door dash order, thus exiting through the sliding glass doors, if BK was watching the house he may have taken his chance to enter, hidden somewhere and waited around 10 mins until the knew XK was in bed before attacking? I can't see a timeline where he attacks MM and KG first.
EDIT
BUT WAIT.
For BK to be walking past DM’s room and towards the sliding doors, he has to be coming from XK’s room. The sliding doors are in the same direction as the staircase leading to the third floor… so either, 1. DM saw BK before he murdered KG and MM. 2. KG and MM were killed first or 3. BK went back to XK’s room after all killing had taken place.
I can’t get the timeline to make sense, I don’t know why I need to but I need to.
