Marco Antonio Guerrero-Lopez, a 39-year-old Hispanic male, tragically lost his life on May 3, 2020, in Rolling Meadows, Illinois. The incident occurred in the early hours of the morning, around 5:00 a.m., when Rolling Meadows police responded to a report of shots fired in the 2000 block of Kirchoff Road. Upon arrival, officers discovered Guerrero-Lopez with a gunshot wound to the abdomen. Despite being transported to Northwest Community Hospital in Arlington Heights and receiving CPR and advanced life support, he was pronounced dead at 5:35 a.m.
The events leading to the shooting involved a complex situation. Guerrero-Lopez had driven his 19-year-old niece and her 21-year-old female friend to a home on South Wilke Road to purchase marijuana. The transaction, involving a $20 sale, was arranged by the 21-year-old woman and Brian Guillen, a 20-year-old male from Rolling Meadows who was on parole for armed robbery. After the purchase, Guillen's girlfriend discovered that the 21-year-old woman had a sexual relationship with Guillen, leading to a confrontation. The parties agreed to meet near Kirchoff Road and Dove Street, where a fight ensued between Guillen's girlfriend and the 21-year-old woman. During the altercation, Guillen allegedly shot Guerrero-Lopez in the abdomen.
Brian Guillen was subsequently charged with first-degree murder in connection with the death of Marco Antonio Guerrero-Lopez. Guillen, who had recently been paroled in January after serving a seven-year sentence for attempted armed robbery, was found hiding under a hot tub in his backyard along with his girlfriend. A .380 caliber gun with five live rounds was discovered near the hiding spot. Guillen was ordered held without bail and was scheduled to appear in court later in May 2020.
The case highlights the tragic consequences of a seemingly minor dispute escalating into violence, resulting in the untimely death of Marco Antonio Guerrero-Lopez. The investigation and legal proceedings surrounding the incident underscore the complexities and challenges faced by law enforcement and the judicial system in addressing such violent crimes.
