A jury found Davis guilty of first-degree murder in December 2025.

During the sentencing hearing, prosecutors presented evidence in aggravation, including testimony from a Lake County sheriff’s correctional officer who said Davis was involved in a physical altercation with multiple inmates in January 2026.

Four victim impact statements were read in court from Berrios’ wife, two daughters and older brother.

Prosecutors said the family described Berrios as a devoted father and husband who loved his family deeply. His daughters spoke about the void left by his death and the milestones they will face without him.

Prosecutors argued Davis and his associates planned the killing on Oct. 3, 2022, targeting an innocent man.

They said Davis planned the attack, including obtaining a stolen car and attempting to conceal his identity by turning his sweatshirt inside out.

Prosecutors sought a natural life sentence, describing Sergio's killing as "gruesome" and "cold-blooded."

What they're saying:

 "As we heard from Sergio's loved ones at the hearing, Sergio was deeply loved as a father, husband, brother, uncle, and friend. This tragic shooting should have never happened. Now, this murderer will likely spend the rest of his life in prison because of his calculated decisions. We know this long sentence will not bring Sergio back, but we hope that it brings some healing to those who loved him. We will always support them," said Lake County State's Attorney Eric Rinehart. 

What's next:

Davis was sentenced to 42 years for first-degree murder, plus a 25-year firearm enhancement, to be served at 100%, for a total of 67 years, prosecutors said.

In a separate case, he was sentenced to six years in prison to be served consecutively.
