San Bernardino

SAN BERNARDINO, Calif. -- Fourteen-year-old Destiny Hull spent Tuesday morning mopping up dried blood from her grandmother's front porch, stains from an evening that began with an act of kindness and ended with an apparent act of vengeance that left a small girl dead and a pregnant woman and her young daughter seriously wounded.

The series of events in San Bernardino began Monday evening when a Good Samaritan who lived in the house -- police won't say who for fear of tainting possible eyewitness accounts -- saw a man beating a woman down the street, charged in and broke up the fight, allowing the woman to escape.
