Rapper arrested after six killed in mass shooting at July 4th parade

A rapper with disturbing songs and music videos has been arrested after six people were killed during a July 4th parade.

Gun violence shook the United States on Monday when a gunman opened fire on a family parade from a rooftop in the Chicago suburb of Highland Park.

The shooting happened just 15 minutes after the 10 a.m. celebrations began, and police made an arrest about 10 hours later.

Robert E Crimo III, 22, was arrested after officers spotted the car he was last driving.

Police then publicly identified Crimo as a “person of interest,” and people were able to find his online accounts – although many of them have since been deactivated.

Crimo, whose nickname is Awake the Rapper, has posted content online including an album called Brainwashed featuring songs titled Dead Again and I Am the Storm.

A music video shows Crimo on a set resembling a classroom, with gunshots and maniacal laughter.

The video for his song Toy Soldier features stick figure animation of a man firing a gun at people and later lying in a pool of blood after apparently being shot by police.

The lyrics to his song Awake include the line: “My deeds will be brave and my thinking is unnecessary, I know what I must do, I know what’s in it, not just for me but for everyone else.”

Crimo comes from an Italian-American family living in Highland Park, Illinois, according to his IMDb page.

His father owns a local deli and once ran – unsuccessfully – for mayor in the affluent neighborhood.

Of the six dead, five are adults. It is not yet known how old the sixth victim is.

Dozens of people were injured and hospitalized, with six still receiving medical attention.

The police have not revealed anything about Crimo’s possible motives.
