NCIS AGENTS FACE A TOUGH INVESTIGATION INTO ONE OF THEIR OWN AFTER A YOUNG MOTHER, THE GIRLFRIEND OF A NAVY PETTY OFFICER, VANISHES

48 HOURS: NCIS: "Body of Evidence"

After a young mother, the girlfriend of a Navy sailor, vanishes, NCIS agents face a difficult investigation into one of their own that will challenge them on every level, on 48 HOURS: NCIS: "Body of Evidence" to be broadcast Tuesday, June 6 (10:00 PM, ET/PT) on the CBS Television Network.

In 1989, Annie Tahan disappeared without a trace. She left behind a newborn daughter and her boyfriend, Michael Paalan. Paalan told police that she had walked out on him. Four years after she disappeared, and with little to go on, police in Charleston, S.C. asked the NCIS for help.

"In working these cases, particularly a missing persons case, it's devastating to the family," says NCIS Special Agent Pete Hughes. "They have no answers."

"We have a motto that we live by," says NCIS Special Agent Jim Grebas. "It's: 'To the living we owe respect, and to the dead we owe the truth.'"

Kathi French, Tahan's friend, didn't believe Paalan's story, so she did whatever she could to get a law enforcement agency to look into the decorated sailor.

"Michael was an evil, evil man," French says. "I know with every fiber in my being that he had done something really bad to her."

But was French right? Did Paalan have something to do with Tahan's disappearance? Agents noted that Paalan was an intelligent electronics surface warfare specialist for the Navy, and he had to be sharp to be in that position. It would take years of challenging investigative work, multi-agency cooperation, surveillance and a sting operation to get answers. Moreover, they were investigating one of their own, making the case even tougher.

"We knew that this was going to be a mental warfare game," Hughes says. "If we're going to solve this thing, we've got to approach it right. Because something terrible happened to Annie Tahan, and we owe it to her."
