Cops hope video taken from an apartment door peephole four months ago will help solve the murders of two tenants who lived next to each other in a Brooklyn housing development .
Police found the bodies of Ana Delvalle, 62, and Basil Gray, 54, just two days apart inside their fifth-floor apartments in the Bushwick Houses in May.
Cops found Delvalle first, on May 11. Her hands were bound and she had been shot in the head several times. Gray’s family found him dead in his apartment on May 13, also shot in the head.
Police offered a $10,000 reward for information leading to an arrest , and on Tuesday, cops released video of three people walking through the hallway around the time the murders took place.
Detectives were looking into whether the killings were linked to an argument Gray had with a man he thought was loitering in the building, dealing drugs, sources said in May.
Delvalle was known to clean the hallways with bleach, sources said, and may have stepped outside her apartment when the gunman shot Gray, sources said.
Police found .380 caliber shell casings in both apartments.
