In 2013, Robert Dahl, right, and Napa contractor Greg Knittel joined forces and opened a brew pub. Six months later, Dahl announced that the brew pub was losing money and abruptly shut the venture down, costing Knittel his investment.
On March 16, 2015, Napa County Sheriff's officers converged on Dahl Vineyards in response to a frantic 911 call. Emad Tawfilis, shot and bleeding, managed to call police while fleeing from Robert Dahl, who was chasing him through his vineyard with a gun.
After killing Emad Tawfilis in full view of Napa County Sheriff's officers, Robert Dahl fled in his vehicle into the hills above his vineyard. As police closed in, he killed himself with a single gunshot to the head.
Here his SUV rests against a tree after his suicide.
