The story about the two women being found dead was announced on the 20th.
If GP had happened to see on the local news on the hotel TV or online, that the two women who told BL to knock it off, stop hitting a woman, had turned up dead, could BL, having been asked by GP if he knew anything about it, perhaps have hastened his trip back to Utah, from the planned 23rd (as GP’s mother believed) to the 20th/21st?
Wait was that the last evening the ladies were seen alive? B/c suddenly BL had a night alone and a hotel room to himself. I was thinking it was a day later though, making the timeline wrong but I might be wrong.
