More than 18 months ago, the body of Odin Lloyd was found in an industrial park in North Attleboro, Massachusetts. Lloyd had been shot seven times near a pile of construction waste. The semipro football player for the Boston Bandits was 27. Days after he was found dead, then-NFL star Aaron Hernandez was arrested and charged with murder. Testimony in the case against Hernandez began this week. Hernandez also faces murder charges in a 2012 double homicide. He has pleaded not guilty. The charges mark the latest turn in Hernandez's downward spiral. Just two years ago, he was one of the NFL's most promising tight ends, inking a $40-million contract extension with the New England Patriots. Friends and fans alike wonder: How could the star player who had more than 900 receiving yards in 2011 now be on trial for murder?

Five years after the collapse of the San Jose gold and COPPER mine that trapped 33 miners for 69 days, CNN correspondent Rosa Flores travels to Chile to speak with three of the miners. She also speaks with the drillers who worked around the clock on their improbable and miraculous rescue. The hour-long CNN Special Report, A Miner Miracle: Five Years After the Chilean Rescue airs tonight, August 4, at 9pmET/PT on CNN and via CNNgo. Jorge Galleguillos can't shake the tragedy from his mind. He was one of the 33 men trapped a half-mile beneath the hard rock of Chile's Atacama Desert. He remembers praying to live while preparing to die. Finally, a small drill broke through to the men, allowing them to send an astounding message: 'All 33 of us are alive.' Their 69 days underground and their triumphant rescue stunned the world who watched it live on television. The men became globe-trotting celebrities with multiple movie and book offers; however, five years later, Galleguillos and most of the miners still live very humble and difficult lives. Many of the men battle demons and have trouble keeping steady work. And no one was ever held accountable for the collapse of the San Jose gold and COPPER mine. During the CNN Special Report, Flores interviews former Chilean President Sebastian Pinera, whose optimism for their rescue rallied a nation and the world. She also speaks with Jeff Hart, the drilling expert who successfully carved a tunnel through the earth and helped save the 33 courageous men.

It's been more than 10 years since Shirley Reine was found dead in her Falmouth, Massachusetts, home. She had been shot just days before she was going to face her stepsons, Todd and Melvin Jr., in court over who would control the family's lucrative trash-hauling business. Shirley came from a family that was no stranger to law enforcement. Her husband, Melvin, who died in 2013, was a convicted arsonist who was suspected, although never charged, in a number of other serious crimes. John Rams Jr., a Wareham resident with a lengthy criminal record, went on trial for Shirley's killing and was acquitted in 2014. Rams told CNN's Randi Kaye that Todd Reine had asked him to kill Shirley and he declined. Todd Reine has not spoken publicly about Shirley Reine's death, and the Reine brothers have never faced any charges in connection with the killing. A CNN special report, "Murder on Cape Cod: Who Shot Shirley Reine?," explores this murder mystery and the legacy of the Reine family.
