James Jerold Koedatich (born June 12, 1948) is an American serial killer who was sentenced to death for the killings of two women in Morris County, New Jersey, which he committed during the final months of 1982, after having been previously paroled for the 1971 murder of his roommate in Florida. Koedatich had killed a fellow inmate in 1973, but that was ruled to be self-defense.
