Caesar Fuentes, 23, is charged with first degree reckless homicide with use of a dangerous weapon in connection to the shooting death of 24-year-old Andre Nicholson. Investigators say the two were arguing over who had the better basketball team, and Fuentes is accused of shooting Nicholson six times.

Following the shooting, Fuentes resigned from the Hales Corners Fire Department. 

During the preliminary hearing Wednesday, Fuentes' attorney pleaded not guilty to the charges. However, the judge found probable cause to send him to trial. 

Fuentes is scheduled to appear back in court on Jan. 12.
