MADISON, Wis. (WMTV) -- The man accused of killing Nicholas Day in what the Dane Co. Sheriff described as a "cold and calculated act" is not competent to stand trial, a Dane Co. court ruled.
After hearing testimony from a doctor, a Dane Co. judge determined Riley Berg was not competent for his upcoming trial. However, the court also found he will likely be able to stand trial in the future and ordered him into treatment.
Berg, 21, is charged with first degree homicide in the killing of Nicholas Day on County Highway JG near Blue Mounds on January . He pleaded not guilty in late February.
According to a criminal complaint filed Monday, a woman saw Day running on County Highway JG around 12:58 p.m. on Jan. 15 as she was driving toward Stewart County Park.
She told detectives she forgot something at home, turned around, and six minutes later, saw a hat on the road. She said she then found Day’s body in the ditch.
An examiner with the Dane County Medical Examiner’s Office prounounced Day deceased and authorities believed his death was a hit-and-run. During the autopsy, a forensic pathologist found “11 incised wounds of the neck and a gunshot wound of the torso.”
Court documents state a detective saw Berg’s vehicle pull into Tyrol Basin at 12:51 p.m. and leave a minute later on the day of Nicholas Day’s death. The detective noted it takes roughly 5 minutes from when Berg left the parking lot to where Day’s body was found.
A detective said he saw Berg’s vehicle at Stewart Lake County Park on Jan. 24 and contacted him. Court documents state while he was asked if he was at the ski area, Berg said he wasn’t sure if he was there that day.
During the investigation, detectives said they learned Berg hunted “every day” and had access to guns and would have a knife on him if he was out hunting.
According to the criminal complaint, Berg was diagnosed with schizophrenia but is reportedly not symptomatic and takes medication.
During a search of Berg’s vehicle on Feb. 13, detectives reportedly found a blood stain containing Day’s DNA on the driver seat belt strap.
Detectives said when they interviewed Berg after searching his vehicle, he told them he did not know Day and Day has never been in his house or his car.
A motive for Day’s death was not mentioned in the criminal complaint.
If convicted, he could spend the rest of his life in prison.
