Authorities are investigating the police-involved fatal shooting of a 47-year-old Leonia man who officials say robbed a pharmacy.

Bergen County Prosecutor John L. Molinelli says Rickey L. McFadden was killed Sunday shortly after he entered a CVS pharmacy around 4:30 p.m. with a large knife, taking cash and other goods. After leaving the pharmacy, McFadden headed on foot down the street and was pursued by several officers.

Molinelli says officers from the borough and Palisades Park attempted to apprehend McFadden, who still had the knife. During a confrontation, McFadden was shot and killed.

The prosecutor says three officers were involved. Their identities are known by their police chiefs in Leonia and Palisades Park and they've retained legal counsel. He declined to disclose further details.
