It's been 15 months since the family of 21-year-old Allison Rice laid the college student to rest, and police are no closer to arresting her killer.

Rice was found shot dead in her car, just three miles from campus. The LSU student was stopped at a railroad crossing for a train when witnesses say the killer or killers walked up to Rice's car and started shooting.

Police say she may have been in the middle of turning around when the shots were fired. Police also say there’s no sign anything was stolen from Rice's car.  

There is a  $50,000 reward for information leading to an arrest.
