...for 6/17-only thread...
IIRC, Brian B. states shovel day is 6/17 or 6/18 and Casey borrows shovel ~1:30-2:30PM or as late as maybe 3PM...not quite certain, but, she has it for ~1hr.
Consider the following ping, fb & computer forensic info and which may support shovel day as 6/17 or 6/18.
All times are approximate based on pings entering/leaving area...

NOTE: Brian B. comments on seeing the PONTIAC backed into the garage. 6/17 events suggest Casey had to change cars between 4:05PM and 5:20PM to have Tony's GC @ Chris' by 5:20. Hmmmmm
