Trying to be Good Samaritans cost two members of a Montana family their lives and left their daughter wounded.
The triple shooting happened in the town of Pryor, Montana, about 30 miles south of Billings.
The suspect, 18-year-old Jesus Deniz Mendoza, is expected in federal court Friday.
The family was shot when they returned to help Mendoza, whose car was seen stopped along side a road on the Crow Indian Reservation on Wednesday morning, according to an FBI criminal complaint.
The daughter said her mother “came to her house and told her that there was a guy that needed assistance.”
The mother, father and daughter then returned to where Mendoza’s car was parked, the court document says.
Mendoza pulled a gun on them and ordered them out of their car. He demanded money, but the family said it didn’t have any, according to the FBI.
