Man Who Stabbed Mother and Her Four Children To Death May Have Been Jealous of Their Lifestyle

Chinese immigrant Ming Don Chen has implicated himself in the killings

Authorities believe a Chinese immigrant who fatally stabbed a mother and her four children in their Brooklyn home Saturday night was jealous that the family had been so much more successful in America than him. 

"The family had too much. Their income (and) lifestyle was better than his," a police source told the New York Post Sunday.
