Residents in Pardo's Uniondale neighborhood said police flooded the area Sunday and detectives asked if they had heard any crying or screaming coming from the home.

"I was here, but I didn't hear any crying," said one man, who has lived in the neighborhood for five years and declined to give his name. "I'm very sad -- a young baby. It's incredible, man."

Another neighbor said a detective knocked on her door late Sunday afternoon and asked if she had heard any noise coming from the Pardo home.

"He just came and said, 'Did you hear a noise or a scream like that?' and we said, 'No,' " said the woman, who also did not want to give her name.
