HotMessMomTV@HotMessMomTV1I'm sure officers already knew- and were just checking in on #BryanKohberger while they continued investigation. I get the gag order pre-trial, but hope they release it once the trial starts #Idaho4907I'm sure officers already knew- and were just checking in on #BryanKohberger while they continued investigation. I get the gag order pre-trial, but hope they release it once the trial starts 🙏 #Idaho4 https://t.co/Nbs07lW9vIAnother student, Thomas Arntz, said that Bryan was a mean-spirited bully. He added that while he never thought Kohberger would kill anyone, the murders didn't really surprise him.As per the Independent, Idaho authorities have not disclosed a potential motive behind the slayings. However, they did find Kohberger's DNA on a knife sheath recovered at the scene of the crime. If convicted of the killings, he could potentially face the death penalty.
