A monkey that got away after a truck flipped over on a Mississippi road last week was killed early Sunday. A woman shot it because she was worried about her kids' safety. Jessica Bond Ferguson's 16-year-old son woke her up Sunday. He thought he saw a monkey running in their yard near Heidelberg Mississippi. She got up, took her gun and phone, and went outside. She spotted the monkey about 60 feet away. 

Bond Ferguson and others had been told the escaped monkeys carried diseases so she fired her gun."I took action that any mom would take to keep her kids safe," Bond Ferguson, who has five children with ages between 4 and 16, said to The Associated Press. "I fired at it and it didn't move so I fired again. That's when it stepped back and fell down."
