Chet Walker and the Laboratory

Dave is played by s john loner who lived 19 19 through 2006 mostly did small roles but appears in Hitchcock's Marnie from 64. Chet analyzes the luminous residue and the blood left behind at the crime scene he discovers that the blood is not blood at all it's some kind of artificial concoction containing microscopic crystals. The reporter threatens to misspell Chet Walker's name which this sent me down a rabbit hole,  I'm gonna say like Cheb Wonker yeah it's a delicate balance.
