The NYPD is offering a $10,000 reward to anyone with information on a double homicide in Brooklyn.

This poster has sprung up throughout the Prospect-Lefferts Gardens neighborhood where 59-year-old Hazel Brown and 65-year-old Stephenson Bonaparte were stabbed to death.

Police found the couple outside their home on Winthrop Street last Wednesday.

Investigators say they were about to enter their home when they were attacked and then robbed.

Witnesses say they saw a man in a ski mask running from the scene.
