Marco Antonio Guerrero-Lopez, a 39-year-old Hispanic man, was killed early on May 3, 2020, in Rolling Meadows, Illinois. Police responded at about 5:00 a.m. to shots fired in the 2000 block of Kirchoff Road and found Guerrero-Lopez with a gunshot wound to the abdomen. He was taken to Northwest Community Hospital in Arlington Heights, where CPR and advanced life support were attempted; he was pronounced dead at 5:35 a.m.

The sale had been arranged by the 21-year-old woman and Brian Guillen, a 20-year-old Rolling Meadows man on parole for armed robbery. After the purchase, Guillen’s girlfriend discovered the 21-year-old woman had a sexual relationship with Guillen, and a confrontation was arranged near Kirchoff Road and Dove Street. During a fight between Guillen’s girlfriend and the 21-year-old woman, Guillen allegedly shot Guerrero-Lopez in the abdomen.

He was ordered held without bail and had a court appearance scheduled later in May 2020. If anyone knew Marco or has information about the events that night, please share what is known.
