Court records indicate Adonis Gillis pleaded guilty to a lesser charge of second degree murder on May 22. He also pleaded guilty to burglary and robbery with a firearm. A judge will sentence him in August.
According to documents, the charges carry a minimum or 25 years in prison and a maximum of life in prison but prosecutors can make a different recommendation.
Boca Raton police arrested Gillis and three other men in the drug-related robbery turned shooting that killed Nicholas Acosta in December 2015. The shooting happened at a student-only apartment complex east of FAU.
Roderick Woods also agreed to a plea deal.
Donovan Henry took his case to trial. A jury convicted him and a judge sentenced Henry to 35 years in prison.
The suspected shooter, Alexander Gillis, will be in court later this week.
