I've tried diligently to catch up. I surrender. Where's the blasted PAUSE button??? Meanwhile - ALL MOO - totally out of order, since I'm never current with posts...
DB leaving door unlocked - I never saw that as a confirmed fact? IF someone came in window, why not unlock door + exit through it? IF that's the scenario, it may have caused nothing for the dog to bark at, window in front, dog in back + it may have taken 5 minutes total. In the window, flip light on, grab baby, flip next light on, see + grab cell phones, unlock + out the door. I'm OCD about windows, doors + lights. All the same, I've been exhausted or sick enough to forget 1 or all. I'd absolutely have windows open with the weather that night. I have no idea what their "routine" was? Doesn't matter, that night was the 1st of a new routine + sick baby + I assume 2 boys in school next day + I assume 1 exhausted mom.
Re-enactment - I saw 3 different approaches to entering via window - ALL successful. 1st something to step on, up + in, no problem. I didn't observe "help", looked like "spotting" in case he slipped / fell. 2nd, "free climb", no boost, no step, just hoist himself, up, over, in, slick + quick. He'd even pulled up + put a foot on the sill first. 3rd with helper, boosting. I see no problem with anyone getting in that window easily. Personal experience - I'm NOT agile, young or small, + had a spell of locking myself out + window higher than this without ledge. For convenience I used a lawn chair to climb closer to the sill + tumble in, not graceful, but worked. I was also able to do this with no chair, step or help, but more of a struggle. If someone has enough desire to get in a window, it's easily doable. I think LE knew this already, so what was the point? To do it silently or without leaving fibers or WHAT?
Questions - What time did JI leave the home to go to work? What time was he scheduled to arrive home in the morning? When he returned home, which entrance did he use? Was this to be his first of many overnight shifts or a one time thing? What time did the younger boys go to bed? Did the youngest go to his bed first + later to Mom's or did he start sleeping in her bed? Did DB give any medicine to Lisa? What time? What time were neighbors visiting + what time did they leave?
Wishing baby Lisa is found safe, soon.
Now back to grumbling + cussing from my armchair POV...
