UPDATE: Authorities have found the three children who were kidnapped from California earlier this month.
The children's mother, Kimberly Harvill, was found shot to death on August 14th.
The children, ages two to five years old, were left at Motel 6 in Albuquerque, New Mexico.
A good samaritan in care of the children called authorities.
Lieutenant Joe Mendoza with the Los Angeles Sheriff's Department says the main goal is to get the kids back home.
"The police were able to locate the children and they are now in the custody of children's services in the state of New Mexico."
"Our law enforcement here, our investigators, are making arrangements to bring those kids back to California and they're working with the Department of Children's Services in California to make sure that we bring those kids back safely," said Lieutenant Mendoza.
Arrest warrants have been issued for Harvill's sister Brittany Humphrey, and Joshua Robertson.
The pair could be driving a green metallic 1999 Ford Expedition with California plate number 7BEK024, or paper plates, heading east, north or south from Albuquerque
The suspects are considered "armed and dangerous." Do not approach the suspects if seen, call local law enforcement or 911.
