His name has not yet been released. Sheriff Anderson says the man appears to have shot himself in the head.
Authorities say the man shot and killed the woman and her attorney at Ducey's Restaurant.
Deputies have identified the attorney as Judy Soley of Fresno.
Friends of the woman say she and Soley were having lunch at Ducey's, after spending the morning in court for her divorce case.
Friends believe the suspect is the woman's estranged husband.
"The last few times I had seen him, he didn't seem to be himself and i know they were struggling and going through a tough time," Jerry Reed said.
Judy Soley was a prominent attorney who practiced family law in Fresno for almost 40 years.
An injury at birth left her in a wheelchair. She was the first woman to serve as president of the Fresno County Bar Association.
