Christa Pike was 18-years-old when she thought her 19-year-old job corps classmate, Colleen Slemmer, was trying to steal her boyfriend, Tadaryl Shipp. Pike spent over 30-minutes beating Colleen Slemmer with her hands and feet, as well as a box cutter and a meat cleaver. Slemmer tried to escape. Shipp,17, caught her so Pike could continue the beating. Pike carved a pentagram into Slemmer's chest, used the box cutter to slice her throat. When she didn't die, Pike picked up a chunk of asphalt and slammed it onto Slemmer's head. The next day Pike brought a piece of Slemmer's skull to breakfast and told classmates what she had done. Convicted of murder and sentenced to death, Christa Pike now wants a judge to vacate her death sentence. Joseph Scott Morgan and Dave Mack detail the story that Joe Scott says is the worst case he has ever seen.    Transcript Highlights  00:00:31 Joseph Scott Morgan says he has never seen a crime so vile  00:02:10 Woman on death row in Tennessee   00:05:16 Talk about dynamic between suspects and victim  00:10:09 Description of box cutter and meat cleaver   00:15:03 Discussion of pentagram carved into chest  00:20:56 Description of wounds to victim  00:25:15 Talk about how to occult and satanism factor into case  00:30:40 Description of taking piece of skull as a trophy  00:35:50 Discussion about letting murderer out of prison  00:39:15 Talk about sadistic murder See omnystudio.com/listener for privacy information.
