Beginning next week, an Arroyo Grande man will stand trial for the murder of 26-year-old Kristen Marti. Her body was found in Prefumo Canyon. Police believe she was murdered nearby in January.
36-year-old Robert Koehler faces a single count of murder. He was extradited from Minneapolis, where he and his wife had recently moved. Marti was a heroin addict who supported her habit through prostitution.
The judge found probable cause to try Koehler for murder. He’ll return to court for arraignment on next Monday, October 15th.
