Salem police have identified three children and their mother who died in what is being called a murder-suicide in which the father also died.
The children's father was found dead in a car in Cottage Grove. He has not yet been officially identified.
Police say an infant girl 3 to 4 months old, a 1-year-old girl and a 3-year-old girl were killed, as was their 26-year-old mother, Natalya Lazukin.
The infant died of asphyxiation and the others died by gunshot.
They were found in their house on Tuesday.
The deceased girls were identified as infant Sefi Lazukin, 1-year-old Zoe Lazukin and 3-year-old Angelica Lazukin.
A sixth person whose body was found on the street a quarter mile north of the house was identified Wednesday afternoon as 21-year-old Devin Matlock.
