Geoff Dean

California’s Ventura County Police Sheriff, Mr. Geoff Dean, in whose domain a gunman killed 12 people and injured scores, has revealed his intention to resign from office.

Dean made this known to a CBS News reporter on Thursday.

He had told the reporter, “I am no longer the sheriff, tomorrow at midnight;” to which the reporter responded, “You are retiring tomorrow?” and Dean replied, “I am.”

Meanwhile, the gunman who killed 12 people in a crowded California country music bar has been identified as 28-year-old Ian David Long, a former Marine, the local sheriff said Thursday.

“We have had several contacts with Mr. Long over the years, minor events, a traffic collision,” Dean said, adding that deputies were called to his house for a disturbance in April this year and “felt he might be suffering from PTSD.”

The suspect was found deceased at the scene, in the city of Thousand Oaks northwest of downtown Los Angeles.

“We believe he shot himself,” Dean said.
