A mother and daughter are claiming they killed five family members because everyone in the household wanted to die, police say. Sources say 45-year-old Shana Decree, and her daughter, 19-year-old Dominique Decree, strangled the victims over the past couple of days in their Morrisville apartment. Shana and Dominique Decree have been charged with five counts of criminal homicide and one count of conspiracy to commit criminal homicide.

The victims include Shana Decree’s children — 25-year-old Naa’Irah Smith, and 13-year-old Damon Decree Jr. — as well as Shana Decree’s sister, 42-year-old Jamilla Campbell, and Campbell’s 9-year-old twin daughters, Imani and Erika Allen.
