The Santa Cruz County District Attorney’s office has unsealed a warrant issued earlier this summer, for a 5th-suspect in the fatal stabbing of a 16-year-old in Santa Cruz last fall. 23-year-old Capitola resident Ivan Ramirez is wanted by authorities for murder and gang participation. Ramirez is believed to be traveling somewhere in Southern California. A 4th-suspect is also wanted for the murder of Tyler Tenorio last October. That man, Paulo Luna, is believed to have fled to Mexico. The 3-other suspects in the case have been arrested, and are set for a preliminary hearing in November. All-3 have pleaded not guilty to murder charges with gang enhancements.
