48 Hours: NCIS

In June 2001, the bodies of Navy Petty Officer Lea Anne Brown and her friend Michael Patten, a bank employee, were found in the woods off a rural road in Accokeek, Maryland. Both had been shot twice in the head. They appeared to be targeted murders -- but why? Neither had any connections to any criminal activity, and there wasn't anything else that would make them obvious targets of such a vicious crime.
