Napa Valley winemaker kills investor and shortly after kills himself; this was all witnessed by police.

47 Year old Robert Dahl (winemaker) shot 48 year old Emad Tawfilis (investor) on Monday March 16, 2015. Tawfilis had lent Dahl $1.2 million to finance a Napa Valley winery.  But last year Tawfilis sued Dahl after learning that the business he had invested in (Patio Wine) was invalid. Dahl was using that money borrowed in a Napa craft brewery that at that time according to the Times was losing $100,000 a month.  Police say Dahl asked to meet Tawfilis at Dahl vineyards in Yountville, California on Monday to discuss terms off a settlement.  The encounter was just a setup to ambush and kill Emad. Once there authorities say Dahl pulled a gun and chased Emad in his suv and when Emad tripped and fell Dahl got off the car and shot him. Dahl got back in his car and crashed; when police got closer they discovered Dahl had shot himself as well.
