There are too many variables to consider dispersal without doing dna testing against parentage or other relations.

If the mother was shot during the past season, new research in the past couple years suggests that the offspring are less likely to disperse, and remain in the area they were born.

It may have been Ozaga or possibly Alscheimer that did that research.

The end of line is dna testing, it is the only way they will find out. And I am sure they will do that if deemed necessary.
