A little more than one week ago, U.S. Border Patrol agents took four men into custody near Whitefish after they allegedly made an illegal border crossing from Canada into the U.S.
Three remain in custody, including one accused of murder in Canada, but one walked away before agents fully realized who he was.
Now, law enforcement officers are looking for a man named Naseem Ali Saleh Mohammed, 22. Mohammed is also known as Ahmed Bati, according to charging documents filed in U.S. District Court in Missoula. Mohammed is charged with improper entry by an alien.
