District Attorney Dan Dow announced today that a San Luis Obispo County jury has convicted Robert W. Koehler, IV (40) for the first degree murder of 26-year-old Kristen Marti on January 9, 2018.

"Today's verdict has brought justice for Kristen Marti and her loved ones who still grieve her loss. We are grateful for the jury's attentiveness and hard work over the past eight weeks," said District Attorney Dan Dow.
