Came across this old case, some interesting similarities. (Not saying JR will have the same outcome, just found it interesting)
35-Anne Dunlap Murder (1995)
Anne L. Barber Dunlap (June 12, 1964 - ca. December 30, 1995) was the victim of an unsolved murder in Minneapolis, Minnesota. On December 30, 1995, she was last seen at her parents' home (where she and her husband were living temporarily) by her husband Brad Dunlap, whom she married in 1987. According to Brad Dunlap, she returned from a noon lunch with friends and then left at 2:30 p.m. for shopping at Mall of America. Police could not verify that Anne had been at the mall, and Bloomington, Minnesota police chief Bob Lutz declared, "we have not found any evidence that the Mall of America or the city of Bloomington played any part in this homicide." (A private investigator working for Brad Dunlap claimed to have located "more than two" eyewitnesses who would testify that Anne was at Mall of America on the afternoon of December 30.) She did not return home around 4:30 p.m. as agreed. At about 8:00 a.m. on January 1, 1996, a group of Anne's friends found her maroon 1997 Toyota Celica in the parking lot of the KMart store at 10 West Lake Street in Minneapolis, [B]unlocked with the keys [/B]inside. A bloodhound followed Anne's scent to the back of the store, where the trail ended. The car was towed and police investigators found her body in the trunk. Anne had repeatedly been stabbed in the throat and neck. The police officer who opened the trunk said there was "a lot of blood." Media reports indicated that Anne's wedding ring was missing and that she had not been sexually assaulted.
