Shakita Mangham and Furaha Love, both 25, will be charged with involuntary manslaughter, reckless endangerment, endangering the welfare of children and making false reports to police, the Pittsburgh Post-Gazette reported.
Mangham lived in the Larimer, Pa., house that burned at 1:20 a.m. June 12 with her four children, Dezekiah Holyfield, 3; Cedano Holyfield Jr., 4; and Daekia Holyfield, 7; who died, and her son, Jevon Irwin, 8, who did not, the Post-Gazette reported.
Two of Love's three children -- Azequel Rankin, 5; and Andre Rankin, 6 -- died in the fire. Her 8-year-old son, Huedon Chambliss, survived.
The two mothers initially told police the children were with a babysitter.
"This is definitely a crime," District Attorney Stephen A. Zappala Jr. told the Post-Gazette.
A defense lawyer disagreed.
"A fire broke out. She didn't set that fire," Love's lawyer, Ernest Sharif, told the Pittsburgh Tribune-Review. "She may have wanted to be there when the fire started, but even if she were there, the children might not have lived."
