YOUNTVILLE (KRON) — Money may have been behind Monday’s murder-suicide in Yountville.

Deputies with the Napa County Sheriff’s Office are still investigating Tuesday’s shooting, but think they may have found the motive for the murder.

Authorities believe vintner Robert Dahl shot his former business investor, Emad Tawfilis, in a vineyard overlooking Highway 29.

Dalh then ran into the hills between Napa and Sonoma valleys before shooting himself.

Kousha Berokim, a Los Angeles attorney who represented Dahl, says her client and Tawfilis had met Monday morning at Dahl’s winery to discuss a loan dispute.

According to reports, Tawfilis was suing his Dahl, claiming Dahl defrauded him out of more than $1 million.
