Police release new surveillance video in connection with a double homicide in Brooklyn.
Investigators want to track down and question three people.
Detectives say they were seen inside the Bushwick Houses, where two neighbors were killed, execution-style back in May.
Police say 62-year-old Ana Delvalle was found tied up and fatally shot in her apartment.
Then two days later, investigators found her next-door neighbor, Basil Gray, shot and killed with the same caliber gun.
Police still don't know why they were targeted.
A $10,000 reward is being offered for any information that leads to an arrest.
Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-8477, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
