A suburban Detroit man was sentenced Wednesday to at least 17 years in prison for killing an unarmed woman who appeared on his porch before dawn.

A suburban homeowner who opened his front door and blasted an unarmed woman on his porch should have called police instead of becoming "judge, jury and executioner," a prosecutor said Wednesday.

The parents of a 19-year-old woman who was shot in the face on the porch of a suburban Detroit home say they find it hard to believe their daughter posed a threat to the man charged in her death.
