Gyovanny Arzuaga, a 24-year-old Hispanic man, was killed on June 19, 2021, in Chicago’s Humboldt Park during Puerto Rican Day Parade celebrations. Arzuaga and his girlfriend, Yasmin Perez, were involved in a minor traffic collision on Division Street near Spaulding Avenue. According to reports, a group surrounded their vehicle, pulled the couple out and beat them; during the attack Anthony Lorenzi, 34, allegedly shot Arzuaga at point-blank range. Perez was also shot and died a few days later.

Chicago police, with help from the U.S. Marshals Service, say surveillance footage and other investigative techniques led to Lorenzi’s arrest in San Diego on July 9, 2021, and his extradition to Chicago on a first-degree murder charge. Authorities have said they do not believe the attack was a race-based hate crime and have not confirmed gang ties. Police are still seeking other people involved. A GoFundMe was started to help the victims’ children.

Are there witnesses or anyone with information about who else was involved in the attack?
