Kibbe was known as the I-5 Strangler, who picked up seven of his eight victims along the freeways around Sacramento. His first known victim was killed in September 1977, with the final confirmed woman he strangled dying almost exactly a decade later.
He was convicted of the 1987 murder of 17-year-old runaway Darcine Frackenpohl in 1991
