    MH370

    Investigation puzzle: Is it a key clue or a minor detail? Malaysia's prime minister said that a small chuck of plane wing found in the Indian Ocean belongs to Malaysia Airlines Flight 370 which disappeared in March 2014.

    HOOKUP SENTENCE

    Let's think about this: A 19-year-old man put on the sex offender registry after having sex with a 14 year-old girl, who lied about her age, may get a new sentence. The judge has agreed to reconsider, which may knock the man off the registry. The young man was given a 90-day jail sentence, five years probation and was placed on the sex offender's registry in Indiana and Michigan for the next 25 years. Even though the girl lied, that's not a defense under current law. The teens met on a dating hookup app.

    JON STEWART

    Thank you and goodnight: Jon Stewart bows out of the "The Daily Show" tonight after 16 years behind the "fake news" anchor desk. The pioneering program used political satire and comedy to slay the dragons of American culture and in the process became a news source for a new generation. Comedy Central's flagship show goes on hiatus until the end of September when Trevor Noah takes the reins.
