NCIS AGENTS TAKE VIEWERS INSIDE TWO MURDER CASES FILLED WITH TWISTED RELATIONSHIPS, GREED, LIES AND DOUBLE-LIVES, IN THE BACK-TO-BACK THIRD SEASON PREMIERE OF "NCIS: THE CASES THEY CAN'T FORGET"

Wednesday, May 29

Naval Criminal Investigative Service agents take viewers inside two unusual murder cases that are filled with twisted relationships, greed, lies and double-lives, in two back-to-back editions of NCIS: THE CASES THEY CAN'T FORGET, to be broadcast Wednesday, May 29 (9:00-11:00 PM, ET/PT) on the CBS Television Network.

NCIS: THE CASES THEY CAN'T FORGET returns for a third season with a special two-hour premiere and with Rocky Carroll as the on-camera host. The series features a slate of the biggest cases handled by the real-life Naval Criminal Investigative Service. These are the kinds of challenging investigations that have inspired cases on CBS Entertainment's successful primetime series NCIS, broadcast television's #1 drama, as well as NCIS: LOS ANGELES and NCIS: NEW ORLEANS. The previous name of the series was 48 HOURS: NCIS.

NCIS agents take viewers inside the mysterious case of Cory Allen Voss, a young Navy communications officer murdered after using an ATM in Virginia in "Road Map to Murder," to be broadcast at 9:00 PM, ET/PT on the CBS Television Network. The investigation - a collaboration with the Newport News Police Department - would lead the agents on a trail of twisted relationships, lies and secret double-lives. That trail would lead to a hospital, where two of the suspects met as they served as medical guinea pigs testing drugs. Investigators would spend months listening to wire taps and conduct around-the-clock surveillance of their suspects. Eight months after Voss was killed, two men and a woman were arrested and charged with murder.

And at 10:00 PM, NCIS agents reveal the challenging detective work that went into cracking the unusual and calculated murder of Lt. Lee Hartley, who fell mysteriously ill while serving aboard the USS Forrestal while deployed in the Mediterranean in "Heartless." Hartley's illness baffled doctors, and he was airlifted to a Naval hospital in Mayport, Fla. His new bride, Pamela, was beside her husband the whole time. Months after he fell ill, Hartley died. An autopsy would later reveal he died of acute arsenic poisoning. How did that happen? Investigators, as routine, turned to his new wife as a possible suspect. But toxicology indicated Hartley was poisoned while on duty aboard the Forrestal, with 6,000 potential suspects. The case went cold after a year. Then, nearly 13 years after Hartley died, the NCIS cold case squad reopened the old casefile. Dozens of potential witnesses, family and friends were re-interviewed before agents would close in on a suspect, with an unusual motive.
