Man arrested after girl, 13, fatally shot in Milwaukee home

13-year-old girl was killed in her bedroom when shots were fired into her Milwaukee home and police are trying to figure out if it was a random attack or if someone in the house was targeted.

Police arrested a 26-year-old man in the Monday night shooting, but no charges have been filed.

Police did not reveal his identity, and said they don't know yet if the shooting was random or Sandra's house had been targeted.

Milwaukee Mayor Tom Barrett described the senselessness of the violence.

"Sandra Parks, a 13-year-old, went into her bedroom. She never came out alive." Barrett said during news conference outside his office Tuesday.

"Tragically, her death was caused by someone who just decided they were going shoot bullets into her house and she's dead."

No other family members were hurt in the shooting around 8 p.m.

Bernice Parks, Sandra's mother, tearfully told the Milwaukee Journal Sentinel that her daughter "was everything this world is not."

"My baby was not violent. My baby did not like violence," she said.

Barrett said Sandra's death is "part of the insanity" of gun violence in Milwaukee and elsewhere, noting Monday's fatal shootings at a Chicago hospital .

"We don't have leadership at the national level, we haven't had leadership at the state level that say: 'We're going to address this issue,'" he said.

Sandra's death was the city's 95th homicide so far this year.

 In 2017, there were 101 homicides by this point in the year, according to police.

 Barrett said homicides in the city have decreased overall by 25 percent since 2016.
