The FBI and local law enforcement are seeking an Idaho couple whose children are missing to answer questions about their role in the death of a Utah woman in October.

Lori Vallow and Chad Daybell were last seen in Rexburg, Idaho on November 26th after police executed a welfare check seeking Vallow's daughter and Daybell's son.

Neither child has been seen since September.

Law enforcement is also looking into the death of Daybell's former wife Tammy, who was buried in Springville in October but whose death is now considered suspicious.
