The Pennsylvania mother and daughter accused of killing five relatives were motivated by a religious cult, the family's father exclusively claimed to RadarOnline.com.
Shana Decree, 45, and Dominique, 19, each face five counts of criminal homicide and one count of conspiracy to commit criminal homicide. On Monday, Feb. 25, police found five of their family members dead in their Morrisville apartment. The victims ranged in age from 9 to 42.
The crime has since rocked residents within the small Pennsylvania town – but not more so than Shana's own husband, who is also suspect Dominique's father. The shocked parent claimed he's been concerned about the suspects' deranged behavior for months.
"They were absolutely influenced by a cult over the Internet," Damon claimed to RadarOnline.com. "I believe it was the Black Israelites. That's what several of my family members told me."
Damon, who lives hours away in Raleigh, North Carolina, said he began noticing warning signs in the last few months.
"It was fine until Christmas," Damon explained. "I talked to them and everything seemed normal. Starting on Feb. 1, Shana cut all communications. I called every day and they kept going straight to voicemail."
Damon said he and another relative, Tyquilla Campbell, made several calls to police and child and youth services in Buck County to alert them of Shana's abnormal behavior.

"I thought something was really wrong," he said.
Another family member had "found bags with all the kids' stuff outside the house," Damon explained. "I bought my son an Xbox last Christmas and it was bagged up outside."
On Monday, police confirmed Shana's children, Naa'Irah Smith, 25, and Damon Decree Jr., 13, were among the deceased. Shana and her daughter are also accused of murdering Shana's sister, Jamilla Campbell, 42, and Jamilla's 9-year-old twin daughters.
Multiple Pennsylvania agencies are currently investigating the crimes. Morrisville Police Department Chief George McClay told RadarOnline.com on Wednesday that it is the "saddest homicide I've ever had to deal with."
According to criminal affidavits obtained by RadarOnline.com, Buck County Child & Youth Services had been making visits to the home. A worker was unable to enter the apartment on Monday, which led to the discovery of the sick crimes.
Damon claimed his wife and kids were among eight family members living in Section 8 housing suited for three people.
