Christian Soto, the 22-year-old charged in a deadly assault that left four people dead and seven others injured in Rockford, Illinois, will be undergoing a psychiatric evaluation to determine his fitness to stand trial, a judge ruled on Monday. The serious charges against Soto were detailed in a Chicago Tribune report, following a string of violent incidents that rattled a neighborhood on March 27.

During an arraignment that was conducted via video link, Winnebago County Judge Debra Schafer issued the order for the evaluation, pushing Soto's arraignment to May 17. Assistant State’s Attorney Ken LaRue mentioned that a grand jury will convene on Friday to review the case. Efforts to obtain a comment from Soto's attorney, Glenn Jazwiec, were unsuccessful, with telephone and email messages left on Monday going unanswered, ABC 7 Chicago reported.

The attacks by Soto included stabbings, beatings, and one victim being run over by a vehicle. While authorities are yet to pin down a clear motive behind the rampage, The Winnebago County coroner has publicly identified the deceased: Romona Schupbach, 63; her son Jacob Schupbach, 23; mail carrier Jay Larson, 49; and 15-year-old Jenna Newcomb. Soto is reported to have told police after his arrest that he believed the marijuana he smoked with one of the victims, Jacob Schupbach, was "laced with an unknown narcotic" that induced paranoia, according to the Chicago Tribune.

The brutality of the day's events unfolded within minutes. Authorities say after fatally stabbing Schupbach and his mother, Soto used a truck to mow down Larson. He then attacked three people in one home and proceeded to assault Newcomb, her sister, and a friend with a baseball bat in another. This wave of violence was stopped when Soto, after stabbing a woman in another home, was delayed by a driver who intervened, leading to his arrest by Winnebago County sheriff's deputies, as detailed by reports.
