A 14-year-old boy was shot dead in Milwaukee on Friday night, reportedly the aftermath of a Facebook feud about a girl. The shooting happened at 10:30 p.m. local time (11:30 p.m. EDT) on Milwaukee’s east side. Police heard eight or nine shots fired while patrolling a fireworks show on Milwaukee’s lakefront, said the city’s Police Chief Ed Flynn, according to Milwaukee’s WITI-TV. The officers found the boy without a pulse and with a shot to the head. Officers said they were able to bring the boy’s pulse back, but he died later at a Froedert hospital.
