In the California DOJ's “special report” (from...1972? Not sure exactly when it's from but it's later than '71 at least) the Stine suspect is described as follows: 35-45 years, 5 '10, 190 lbs, crew cut, reddish blonde hair, eye glasses w/ plastic frames, parka type jacket, navy blue or black, dark baggy trousers and paunchy stomach.
Compare this with the LB suspect (as per the same special report):
20-30 years, 5 '10 – 6 '2, 220 lbs, brown hair (visible through eye slots in hood), wearing black hood, lightweight windbreaker, dark blue or black, baggy pleated slacks, very sloppily dressed with protruding stomach.
What's striking about the Stine description is the phrase “dark baggy trousers”. This is not mentioned in the original police report, nor in Fouke's memo nor in any newspaper report I can recall having seen. And it echoes the LB description: “baggy pleated slacks”. (Fouke mentions the fact that the Stine suspect's pants were “pleated” but this is not mentioned in the special report.) The second striking phrase is “...and paunchy stomach.” This is not mentioned anywhere else either. The original police report describes the suspect as “heavy”, Fouke says he's “barrel-chested”. There's no explicit mention of his “paunchy stomach” but the latter is, of course, in perfect line with the LB description of a man with “protruding stomach”.
My point? Well, I'm not sure there is one. But as far as I can tell these characteristics, “baggy trousers” and “paunchy stomach”, are not mentioned in any other report or other source pertaining to Stine's murder. They only appear in this special report.
