Prosecutor’s Route Retraced

Electronic toll records show a federal prosecutor’s car took a roundabout route from Maryland to the spot in Pennsylvania where his body was found, investigators say, deepening the mystery surrounding his slaying.

A federal law enforcement official, speaking on condition of anonymity, told Associated Press that Jonathan P. Luna’s car passed through automated toll booths on highways leading toward the Philadelphia area.

Luna, 38, was found stabbed and drowned Thursday in a Lancaster County, Pa., creek, his bloodstained car idling nearby.

Investigators, who said they have found nothing to indicate the crime was linked to any cases he handled, have been looking into his private life.

Luna had traveled to Lancaster County several times in recent months, and authorities were not immediately aware of any work-related business that would have taken him there.

Investigators trying to reconstruct Luna’s final hours released photos of his 2003 silver Honda Accord in the hope that someone would come forward with information. Officials earlier had planned to release a timeline of Luna’s movements, but an official said the information was not ready for release by Monday afternoon.
