The most compelling indication that Helgoth's "suicide" may have been a homicide seems to be that pillow and the trajectory of the bullet that killed him.

Thomas's answer to Jameson's question brings up "chain of custody" of those boots, but WERE THE BOOTS EVER compared to the HI-TEC print regardless of that chain of custody? Does Thomas know anything about those boots or the stun gun? We see evidence of Thomas dismissing the stun gun because "those inside the case didn't think it was a stun gun". He asks Jameson if she has seen those photos or just heard about them. Has he seen them?
