US Marine murder in Okinawa. P4P?

Saw this story this morning and, maybe it’s from spending 15+ years on this forum, but my first thought was “P4P gone wrong.” Their ages and that they were in a hotel are enough for me to guess. We’ll see what comes out in the investigation and innocent until proven guilty, but my confidence is 80%+ I’m reading the tea leaves (pun def intended) correctly.

“Police said Sunday that Lance Cpl. Devin Jacob Ballard, a 20-year-old U.S. Marine stationed at Futenma Air Station in Okinawa, was arrested on suspicion of killing 39-year-old Anna Yagi at a hotel in the island's capital city of Naha early Saturday and stealing her wallet and backpack.”
