Bud and Litina Matlock were young, in love, married, and living happily together in the town of Malvern, Arkansas. Bud coached youth basketball at the local Boys & Girls Club, and was trying to be a great father and husband. His wife Litina was a sweet and loving partner who was focused on caring for their children and creating a good home. On the early evening of November 18 , 2002, Bud had just finished up a meeting at the Boys & Girls Club. While he was still out, intruders came inside their house where they found Litina cooking dinner and folding clothes. They forced her to her knees and shot her once behind the ear, killing her instantly. Soon after, Bud, unaware of what was happening, pulled into his driveway with their 2 year old son Latron in a car seat in the back. As he opened his car door bullets rained down on him from his own porch. Bud managed to get out of the car and get a running start down the road, but he didn't make it very far before he was shot in the back of the head - he died right there on the street. Mercifully, all the bullets missed baby Latron and he was unharmed, but orphaned. There were instantly many suspects, as the rumors around town began swirling that evening. Although one of the more complex cases the CJ team has ever seen, Chief Donnie Taber and Assistant Chief Jim Bailey and the entire Malvern PD have never given up finding Bud and Litina's killers, and bringing them to justice.

Throughout human history, the planet Mars has captured our imagination. Ancient Egyptian astronomers were the first to record the red planet on a chart of the cosmos known as the Senenmut star map. Scholars believe Mars played an important role in Maya astrology that's described in the Dresden Codex. And modern translation of Sumerian and Babylonian origin myths record a cataclysmic event occurring on Mars. Is our fascination with Mars simply because of its striking red color and prominence in the night sky? Or might we have a more profound extraterrestrial connection? For nearly 40 years, probes have been sending information about Mars back to scientists here on Earth. Photographs of the mysterious planet reveal mountain-like formations known as Twin Peaks and a strange, humanoid face carved into Martian rock. Has NASA found definitive signs of life on Mars that they're intentionally keeping from the public?
