(ARMADA) -- Police and FBI agents have been stopping vehicles entering and leaving the village of Armada as they investigate the slaying of a 14-year-old girl whose body was found in a wooded area of the southeastern Michigan community. State police Lt. Mike Shaw says no suspects were in custody Thursday. Police have released a sketch of a person of interest. Investigators searched a home Wednesday in St. Clair County's Wales Township, and Shaw says authorities arrested two men there on drug charges. It's 13 miles east-northeast of Armada, where joggers found April Millsap's body July 24. On Thursday, police and FBI agents were questioning and checking the identification of those driving into and out of Armada.
