Shana Decree, 45, and her daughter Dominique Decree, 19, are charged with five counts of murder and conspiracy.
"We shouldn't see this at all but this is what we get paid for when we come to work," McClay said. "It's a sad day for us. As much as I've seen in my career, it's the saddest case I've ever had."
McClay says it all seems to have started on Saturday, when Child and Youth Services stopped by, but no one answered the door.
"They did not return again until Monday and that's when we discovered the bodies," McClay said.
Around 4 p.m. Monday, police on a wellness check got to Shana and Dominique’s apartment and found the five victims.
Authorities identify them as Shana Decree’s children: Damon Decree Jr., 13, and Naa’Irah Smith, 25; her sister Jamilla Campbell, 42; Jamilla's 9-year-old twin daughters, Erika and Imani Allen.
Weintraub had to pause and compose himself Tuesday afternoon, the emotion clear in his voice, as he read the names of the twins.
"This investigation is ongoing," Weintraub said. "It will be some time before we can determine all of their causes of death."
According to the court documents, both Shana and Dominque say several of the victims were choked to death. Dominique Decree herself had "visible injuries to her neck."
As for possible motive, or whether this may have been a murder-suicide, Weintraub says what the two were thinking would be speculation at this point.
After the bodies were found, police started looking for Jamilla’s 17-year-old son to make sure he was okay. Police say they found him in South Jersey. He recently ran away from home.
