I'm still quietly digging the new season, but what is it with all of sudden the two crimes discovered at the beginning have to be connected to each other?

I thought the first time I saw them do this (the parachuting accident/dead guys on a lawn) it was really cute, but now it seems to be par for the course.

Dead water-logged hooker leads them to the booster and the football player?

Beaten up boy leads them to the electronics store murder?

I like it better when they have a series of standalones running in parallel.
