Michael James Snyder, who became president and CEO of the Red Robin restaurant chain, died of a self-inflicted gunshot Sunday at his residence in Yakima, according to authorities. He was 68.

Authorities aren’t releasing many details about the incident.

Yakima County Coroner Jack Hawkins would only confirm that Snyder had shot himself.

“We’re not releasing a whole lot of information because it was a suicide and we’re looking out for the family,” Hawkins said Tuesday.

Yakima police have a policy not to release details about suicides unless they involve a crime, said interim Chief Gary Jones.

“And we have not found any criminal conduct,” he said.

Snyder and his brother became the first Red Robin franchisees in 1979 and went on to open 14 of the restaurants in Washington, Colorado and Idaho. In 2000, he merged his franchise company with the parent company and took over as CEO and president, posts he held through 2005.
