Hope this isn't a re-post. Tried posting earlier but did not see it appear (1st time posting).
It has been stated before that JW posted several racing related videos on Vimeo (under the name DriverGITS). What I found interesting is that in one of the videos (for the rally race), at one point he is shown observing the race wearing a neon green work vest. He likely had access to these due to track safety rules/regs.
I initially did not think JW was involved in this crime (I wanted to believe he was just an enthusiastic, decent, wannabe race car driver), but there are too many things pointing towards his involvement:
-Was the only person allowed inside the residence (garage) during the time of the crime
-Lied to the police when questioned according to CD
-According to witness, person seen driving Porsche on Thurs. had short, well-groomed hair and was wearing a neon green work vest (vest also found in remnants of burned Porsche)
-Apparently lived in close proximity to DW
-Due to being employed as SS's driver, likely had knowledge of family's schedule
-Was getting old in terms of making his mark as a professional race car driver and needed major funding to support his racing ambitions
