On the morning of Monday, August 21, 2023, the body of 64-year-old Martin Riske was found in the front yard of a residence at 921 W. Irene St., Pahrump, Nevada. The Nye County Sheriff’s Office called the scene suspicious after reporting the interior of the home was covered in blood, consistent with a violent struggle. Detectives determined Riske died of multiple gunshot wounds just after noon and opened a homicide investigation.

Investigators identified a person of interest and later arrested John Vithoulkas in Clark County; he was charged with first-degree murder and held at the Clark County Detention Center pending transfer to Nye County. The motive for the killing remained under investigation. If anyone has information about Riske, his movements that day, or the events at 921 W. Irene St., please contact the Nye County Sheriff’s Office.
