Fairfax County police found the body of Emylee Lonczak on Aug. 23 in the Vienna area, police said. The McLean High School student left home Aug. 21 with two men, then traveled out of the state to purchase drugs, according to a search warrant. Members of the group then used the drug before returning to Fairfax early on Aug. 22 after realizing that Lonczak needed medical attention, according to the search warrant. None was sought.

A police spokesman reached Wednesday evening said police had not received word of the medical examiner's ruling, and he was unsure whether any charges had been filed in the case.
