An Illinois man was arrested this week on suspicion of fatally shooting a 4-year-old boy in Chicago.

According to the Chicago Tribune, the 23-year-old suspect is accused of shooting Garrion Glover Jr. in the victim’s East Chicago apartment earlier this year.

Police Lt. Marguerite Wilder confirmed the suspect’s identity as Lamario E. Delgado-Gonzalez, of Gary, according to the Bloomington Pantagraph.

After Glover was shot and killed on May 11, his family reportedly told authorities he had apparently gotten access to a handgun and shot himself. Records indicate he sustained a gunshot wound to his neck.

A medical examiner later ruled his death a homicide.

As early as June, East Chicago investigators expressed skepticism about some of the testimony they had received up to that point.

According to the Times of Northwestern Indiana, the victim’s mother initially told police a noise woke her from her sleep the day of the shooting and she found her son lying on the floor near the couch.

Another resident was reportedly sleeping on the couch at the time and told police he was also awakened by a noise and saw the boy on the floor.

Delgado-Gonzalez was subsequently identified as a suspect and arrested Sunday with the assistance of agencies including the U.S. Marshals Violent Fugitive Task Force and police from Bloomington and Normal.

The case is now being handled by the Lake County Prosecutor’s Office, Wilder said, adding that the suspect arrested is “the only person charged at this time” in relation to the shooting.

Charges including murder, neglect of a dependent and reckless homicide were filed several months ago in a now-sealed case.
