The mother of a 17-year-old Texas boy is demanding criminal charges be brought against a father who fatally shot her son. The incident occurred last week when the father, who hasn't been identified publicly, was alerted by his four-year-old son that there was someone in his 16-year-old daughter's bedroom.

The man grabbed his gun and entered his daughter's bedroom, where an argument ensued and his daughter reportedly denied knowing Johran McCormick. Police said the man shot McCormick in the head, claiming the teen was reaching for something.

Police said the girl later admitted to sneaking McCormick into the house.

Fox News legal analyst Lis Wiehl discussed the case this afternoon with Bill Hemmer, particularly the question of what charges, if any, chould be brought against the father.

Wiehl went over the "castle doctrine," which in many cases can protect someone from charges for using deadly force inside their home. Wiehl said she could see authorities pursuing a manslaughter charge and at that point, the main factor in the case would be the father's claim that he believed McCormick was an intruder.
