Robert ‘Bobby’ Crimo III, a Chicago-area rapper, has been identified as the person of interest by authorities in the Fourth of July Highland Park parade shooting, that killed six and injured at least 16 others.

One of his music videos, for the song “Toy Soldier,” depicts a man firing a long rifle at people and afterward lying face-down in a pool of blood after allegedly being shot by police. The associated lyric is as follows, “I just want to scream/F*ck this world/Livin’ the dream.”

He also has a page on IMDb where he is listed as the writer, director, composer, producer, and actor in two music videos. In one, he’s rapping on a set designed to look like a little school. He’s sitting at a desk when he reaches into his backpack; the screen goes black, and a gunshot-like sound is heard. He is on his knees and collapses to the floor when the video resumes. He laughs maniacally, dumps shell casings from his hands, and rubs against an American flag.

Crimo has approximately 30 tracks on Spotify and 223 followers on his Facebook “fan club” page.

In one of the recordings, he is shown sitting on his bed with his arms on his knees and facing the camera. The main page of the Pittsburgh Post-Gazette with the headline “Oswald Slain in Jail” is on the wall behind him, most likely referring to the death of JFK assassin Lee Harvey Oswald.

The 22-year-Instagram old’s profile is filled with groups of three black-and-white images of him in various stances.
