Kohberger intended to be caught, perhaps without making it blatantly obvious that he was doing so. The knife sheath placed next to the bodies of his victims was literally a purposeful calling card, along with Kohberger having had to know his DNA was on it. Cell phone pings? A 12 year old would've known better than to take a phone along on a crime spree on this magnitude, along with keeping the phone on your person while staking out intended the victims' residence on multiple occasions
Whatever Kohberger's ultimate goal here is, he absolutely planned to be captured eventually (maybe not quite as soon as he realized), but this was his intention from the get-go. Perhaps reveling in the world-wide attention he has already garnered was one goal, but Kohberger might also harbor some wild delusion that he is somehow far more capable as an individual than Rome's finest legions already arrayed against him.
Yet there can no other explanation for the fundamental mistakes he's made committing this crime, especially considering his academic background.
