KENNEWICK — Kennewick Police have released the names of two children found shot to death Monday in their home.
The children were identified Tuesday as 16-year-old Kaitlin Austin and 12-year-old Ethan Austin, who were sister and brother.
Andrew Austin found the children when he came home Monday. Andrew Austin is the boy's biological father and the girl's stepfather.
An autopsy is scheduled for both on Wednesday.
Investigators continue to canvass the neighborhood, looking for anyone who may have seen or heard what happened.
Investigators say four people were living in the house, the two children and the mother and father.
Police Sgt. Ken Lattin said that while there has been speculation this is a murder-suicide, it is too early to make that conclusion.
