As new details emerged about an unusual abduction case Dan Markel had worked on before his murder, police on Monday released 911 call logs suggesting the prominent law professor and blogger was still moving after he was shot in his car by an unknown assailant and found by a neighbor.

New details obtained by ABC News make clear that nationally renowned law blogger and Florida State University professor Dan Markel was marked for murder at his Tallahassee home, but they deepen the mystery of who committed the crime and why.

It had been a quiet summer in Tallahassee, Florida's capital. Lawmakers and students from the local universities were mostly out of town. But last week, one of the city's most notable and well-liked citizens was killed with a single shot to the head, and no one yet knows why.
