Police have charged 25-year-old Antonio Williams with the deaths of his sister, 6-year-old Nadira Withers of Brooke Jane Drive, as well as 9-year-old Ariana Decree and 6-year-old Ajayah Decree. The Decree sisters are from Palm Street in Newark, New Jersey. They are the daughters of the suspect’s mother’s cousin.

On Friday, around 7:35 a.m, police were called to a house in the 6400 block of Brooke Jane Drive. Withers’ mother had just returned home from work and discovered the victims. The victims were suffering from stab wounds and pronounced dead on the scene.

"It’s very scary because when I hear things like this, I don’t like to sleep at night," said 9-year-old Gisselle Clark, who attended the same school as Nadira Withers.

"I cannot imagine, as a parent myself who has young children and especially daughters, this is definitely heartbreaking," said Shanqueilla Brown after visiting the children's memorial.

"It’s just devastating to know that something like that could happen to little children," said neighbor Billie Hill.

Investigation reveals Williams had sole care and custody of the children at the home overnight into Friday. He has confessed to killing the victims. Detectives are working to establish a motive in this case.

Williams is charged with three counts of first and second murder and related charges. He’s in custody of the Department of Corrections on a no-bond status.
