"For the people that have committed these crimes, I hope they come forward to say what happened," one resident at the Bushwick Houses said.

Residents there said Monday night that they just want answers, with some afraid to go about their normal routines after two neighbors were found shot to death in their homes within days of each other.

"I told my daughter don't open up the door for nobody, and I started walking her in and out the building again," one resident said.

Police posted flyers to ask for help figuring out who killed Ana Delvalle, 62, who was found bound with wire and fatally shot inside her fifth-floor apartment Friday.

Her body was found two days before police discovered Basil Gray, 54, shot to death in a next-door unit. Investigators are now looking into a link.

"We did recover shell casings in both incidents and they were of the same caliber firearm," NYPD Chief of Detectives Dermot Shea said.

The circumstances have left some older residents terrified.

"Sometimes I got to go to the street, sometimes I get out with my doggie," one said.

"You got to be careful — especially the elderly these days," another resident said. "So many things happen with the elderly."

The city police department released a video Monday, reiterating that the NYPD will be there to protect people, hoping to calm fears in the community.

In addition, police have placed more manpower in the area to put residents at ease until the cases are solved.

"We've added a deployment of extra officers to do interior patrols on all the buildings in the Bushwick development," NYPD Chief of Housing James Secreto said. "We have a command post that is manned 24 hours."

Authorities have not made any arrests as of the time of this writing, but a reward is being offered for information related to these cases.
