Five years ago, Nathan Cross strapped on body armour before heading toward a fire hall in North Preston, N.S.

It didn't save him. Someone started shooting at 6:30 p.m. on April 24, 2011, hitting Cross. The 21-year-old man fled, but collapsed nearby on Churchill Terrace. He died before the ambulance could get him to hospital.

"Mr. Cross had been standing outside with a group of people," RCMP Cpl. Jennifer Clarke said today as police renewed their appeal for information about the unsolved killing.

"Investigators believe that there are witnesses who have information that could result in arrests and possible charges."

She wouldn't say if any of the witnesses had come forward, only that police need help to solve the crime.

Cross's case is included in the province's reward list for major unsolved crimes. The program offers up to $150,000 for information leading to arrest and conviction.

Police are urging anyone with information to come forward and speak with investigators. Tips can also be left with CrimeStoppers at 1-800-222-TIPS (8477), texting TIP202 and a message to 274637, or online.

Clarke said nothing linked Cross's death to the recent spate of shootings in the Halifax area.
