A 45-year-old mother and her teenage daughter are behind bars in Pennsylvania, where authorities allege they killed five relatives — including 9-year-old twin sisters — inside a Morrisville apartment as part of what the mom claimed was a murder-suicide pact.

Both Shana Decree and her 19-year-old daughter Dominique Decree face five counts of criminal homicide along with a single count of conspiracy, according to court records obtained by PEOPLE.

The bodies were found Monday afternoon, but investigators have yet to reveal the causes of death for the five victims, including Shana’s two children, Naa’Irah Smith, 25, and Damon Decree Jr., 13.

Also killed were Shana’s sister, Jamilla Campbell, 42, and Campbell’s 9-year-old twin daughters, Imani and Erika Allen.

An affidavit released Tuesday morning alleges Shana claimed to investigators the killings were carried out as part of a murder-suicide pact entered into by everyone living in the apartment.

She allegedly claimed to police that even the children were suicidal, and had said they “wanted to die.”

It remains unclear when exactly the killings occurred.

According to police, Campbell’s 17-year-old son, Joshua Campbell, was not present when the violence commenced.

Speaking to reporters Monday evening, Bucks County District Attorney Matthew Weintraub called the killings “a terrible tragedy.”

The bodies were found during a welfare check on the apartment Monday afternoon.

Police told reporters knocks on the apartment door went unanswered Friday.

Shana Decree is being held without bail. Dominique has not been arraigned yet.

Neither defendant has entered a plea to the charges.

PEOPLE was unable to determine if either has retained legal counsel who could comment on the allegations.
