Authorities have dismissed the case against a 16-year-old boy who was charged in the fatal shooting of a 14-year-old boy shortly after a fireworks display on Milwaukee's lakefront last year.

The 15-year-old was accused of shooting Tariq Akbar in the back of the head on July 3, 2015, because of an online fight over a girl that didn't involve Akbar. Authorities said the then-15-year-old fired suspect fired into a crowd of arguing teens.

A jury was selected in the accused teen's trial Monday, but a prosecutor then moved to dismiss the charges, citing problems with witnesses that left him unable to prove the case beyond a reasonable doubt. The judge approved the request.
