Katherine Kelly Quinones was 25 when she was murdered on November 5, 1986; her body was recovered weeks later on December 21, 1986, in Napa County, California. She is named among the victims of Roger Reece Kibbe, the so-called I-5 Strangler, who preyed on women along Northern California highways, abducting some under the pretext of offering help before assaulting and strangling them.

Investigators and prosecutors tied Katherine’s death into a larger series of killings attributed to Kibbe. His documented pattern included using parachute rigging cord to bind victims, duct tape to silence them, cutting clothing with scissors that had belonged to his mother, and then raping and strangling them before leaving bodies in remote locations. Katherine’s case was one piece of the evidence brought against him.

Kibbe was later convicted of multiple murders and received six consecutive life sentences without parole. Her death remains a grim reminder of the danger posed by a serial offender who targeted vulnerable women along highways. Did anyone who knew Katherine or who lived in Napa County in 1986 notice anything about her movements or acquaintances that could add context to her last days?
