NBC NATIONAL NEWS — A Philadelphia mother is facing murder charges after killing her 1-year-old twins and poisoning her 4-year-old daughter before making an attempt on her own life.
Stacey Smalls, 41, attempted to commit suicide by slitting her own wrists after she allegedly killed her 1-1/2-year-old son Adam and the boy's twin sister Eve -- drowning one and strangling the other, Philadelphia Police said.
Police sources say Stacey Smalls left four notes explaining that she hurt the children because she was apparently upset about an affair her husband was allegedly having.
"She had something that she felt was justification but there is no justification... it's a tragedy two young babies dead and there is no excuse for that," Police Commissioner Charles Ramsey said.
Neighbors said that the father came home Thursday afternoon and called 911.
His twin children were dead, his 4-year-old daughter was poisoned and his wife had slit her wrists, cops said.
Stacey Smalls was taken to Frankford Hospital while the 4-year-old girl was in stable condition at St. Christopher's Hospital, police said.
