He definitely got more than he bargained for.

Via KCRA 3: 

A gunman who targeted a group of families gathered for a Mother's Day celebration at a school in Brazil was fatally shot by an off-duty cop.

Katia Sastre was praised by local officials for her bravery and was credited with saving the day...

Frightening surveillance video of the incident shows the gunman rush toward a group of elementary-age schoolchildren. He tries to grab a bag as women pull their children away.

That's when 42-year-old Sastre, who was with her 7-year-old, pulled out her weapon and shot the robber three times.
