Background
On March 6, 2026, police in St. Charles, Illinois responded to a welfare check for a subject running in and out of traffic on Main Street. When officers approached Licurgo R. Diazsandi, he threw a knife at their marked patrol car, then told the officers “Because you’re a cop” and announced “I got a knife” and “I’m ready to die.” As officers shined flashlights on him, defendant abruptly turned and charged directly at Sergeant Cory Krupke while holding a knife in his right hand in what he later described as “Call of Duty style” with the blade pointing downward. Officer Christopher Morales fired a shot that missed; Sergeant Krupke discharged his taser, incapacitating defendant. During the struggle, defendant attempted to grab an officer’s taser and resisted arrest while shouting threats to kill police officers.
Defendant was charged with attempted first-degree murder of a police officer, two counts of armed violence with a category II weapon, attempt to disarm a peace officer, aggravated assault to a peace officer with a weapon, criminal damage to government property, and resisting arrest. At the initial detention hearing, the circuit court initially found insufficient probable cause on some counts but found probable cause on attempted murder and aggravated assault—both detainable felonies. The court detained defendant as a danger to the community. Defendant appealed under the Pretrial Fairness Act.
At a motion for relief hearing, the court addressed the length of the knife used. The blade measured approximately 2.5 to 3 inches; defendant’s initial judge had found this insufficient for armed violence charges. However, the second judge correctly noted that the armed violence statute’s “of like character” language permits knives shorter than 3 inches to qualify as dangerous weapons when used as deadly weapons in violent crimes. The court affirmed detention, finding no conditions could mitigate the danger defendant posed.
The Court’s Holding
The appellate court affirmed the detention order, holding that the State satisfied all three statutory requirements for pretrial detention based on dangerousness under the Pretrial Fairness Act. First, defendant is charged with detainable, non-probationable felonies—specifically attempted first-degree murder of a police officer. Second, defendant poses a real and present threat to the safety of the community based on his conduct and statements. The court emphasized that defendant’s erratic and dangerous behavior captured in bodycam footage, combined with his explicit statements about wanting to “kill all police” and provoking “suicide by cop,” demonstrated zero regard for the safety of officers and community members who might be harmed.
Third, the court determined that no pretrial release conditions could safely mitigate the danger defendant presents. The court noted that electronic monitoring cannot prevent access to potentially deadly objects, which are ubiquitous in the community. The court also considered defendant’s history: he was on probation for criminal trespass in two cases and under court supervision for retail theft at the time of arrest, with three additional pending misdemeanor cases. However, the court found that defendant’s criminal history alone was not dispositive; rather, the compelling factor was that no pretrial restrictions could prevent him from engaging in the same dangerous conduct or provoking a similar potentially lethal encounter with police.
Key Takeaways
- A knife blade shorter than 3 inches can qualify as a dangerous weapon under the armed violence statute’s “of like character” clause when used as a deadly weapon in violent crimes—blade length alone is not dispositive.
- Conduct demonstrating intent to harm or provoke police, combined with demonstrated violent action and mental health concerns, establishes dangerousness sufficient for pretrial detention.
- Electronic monitoring and other conditions cannot mitigate dangerousness when a defendant demonstrates propensity for violence with weapons that are readily available in the community.
- Suicidal ideation combined with intent to engage law enforcement in violent confrontation—”suicide by cop”—constitutes inherent danger to both police and the community.
Why It Matters
This decision clarifies that courts interpreting weapon-based felonies need not rely solely on technical measurements but may consider the manner and context of weapon use. The opinion rejects a rigid reading of the armed violence statute and recognizes that a 2.5-inch knife, when wielded as defendant wielded it—charging at an officer with intent to harm—constitutes a weapon of like character to those specifically enumerated. This gives prosecutors flexibility in charging dangerous conduct and prevents defendants from evading accountability through technical distinctions about blade length.
The case also demonstrates how Illinois courts balance mental health considerations against public safety in pretrial detention decisions. While the court expressed concern for defendant’s mental health and suicidal ideation, it determined that such conditions, when coupled with violent conduct toward police and explicit threats, do not support release—because the defendant’s condition itself creates danger. The decision reinforces that dangerousness analysis focuses on actual conduct and articulated threats rather than mere speculation, and that once clear and convincing evidence establishes dangerousness, conditions short of detention are insufficient.
