(Lake County, IL) On Monday, October 31, 2022, the murder trial started for a 2019 fatal stabbing of a Round Lake Beach Woman.  

Alonzo Campos Jr., 23, is charged with five counts of first-degree murder and four counts of home invasion, a class x felony.  

Campos was first charged in May 2019, after Round Lake Beach Police responded to a report of shots fired in a Round Lake Beach home. When Officers arrived, they found the victim, Mariana Castro-Tellez, covered in blood. Officers checked the victim for gunshot wounds, but they noticed an incision on the left side of her upper abdomen. Castro-Tellez was pronounced dead at the scene.  

Investigators determined Campos entered the victim’s home and shot her several times with a BB gun before grabbing a kitchen knife and fatally stabbing Catro-Tellez. Campos fled on foot after stabbing the victim. Investigators were able to detect Campos through several home surveillance videos. A relative of the victim was able to identify Campos in the surveillance images.  

The relative claimed that Campos and another person, who resided in the victim’s home, had an ongoing dispute over a video game console. Campos had attempted to collect money for the video game console weeks prior to the murder but was unsuccessful.  

If convicted, the offense of first-degree murder carries up to 60 years, served concurrently. The offense of home invasion carries up to 30 years to be served concurrent with the other charges.  

Campos has been held at the Lake County Jail since May 2019, on a $2 million bond. The trial is expected to continue through the end of the week.
