DuPage County State’s Attorney

April 22, 2021

DuPage County State’s Attorney Robert B. Berlin and Wheaton Chief of Police William Murphy announced today that bond has been set for two individuals for their roles in an apparent fentanyl overdose of a Wheaton man, thirty-two-year-old Nicholas Donzelli. Kalvin Beulle, 31 (d.o.b. 12/9/1989) of Glendale Heights and Nicole Cassata, 23 (d.o.b. 10/31/1997) of the same address, have each been charged with one count of Drug Induced Homicide, a Class X Felony and one count of Manufacture/Delivery of a controlled Substance – Cocaine, a Class X Felony. In addition, Beulle has also been charged with one count of Manufacture/Delivery of a controlled Substance – Fentanyl/Amphetamine, a Class 2 Felony. On April 19, 2021, Judge Michael Fleming issued a $100,000 with 10% to apply arrest warrant for Beulle and a $20,000 arrest warrant for Cassata. Yesterday afternoon, Cassata posted the necessary 10%, or $2,000, at the Wheaton Police Department and was released from custody. Beulle appeared in Bond Court this morning in front of Judge Jeffrey MacKay who set bond at $100,000, in accordance with the previously issued arrest warrant.

On August 3, 2020, at approximately 11:58 p.m., Wheaton police officers responded to a residence on Rossini Court for a well-being check. Upon their arrival, officers found Donzelli deceased on the living room couch, the suspected victim of a drug overdose. Officers also found numerous drugs in the residence. Through the course of their investigation, Wheaton police identified Beulle and Cassata as the individuals who allegedly supplied Donzelli with the illegal drugs. It is alleged that on August 2, 2020, Beulle was not answering his phone so Donzelli texted Cassata to purchase drugs. It is further alleged that on August 3, 2020, Donzelli again purchased drugs from the pair. It is alleged that the drugs Donzelli purchased from the pair tested positive for fentanyl. It is further alleged that Donzelli ingested the drugs containing fentanyl and died as a result. 

“Illicit drug use continues to be a drain on society which was responsible for 112 opioid overdose deaths in DuPage County in 2020, a 17% increase from 2019. We must put an end to these senseless deaths. Fentanyl is an extremely powerful, drug that can kill a first-time user. I would like to thank the Wheaton Police Department, DuMEG and Assistant State’s Attorney Adam Frahm for their outstanding collaborative efforts which led to today’s charges.”

“Our detectives worked tirelessly to identify the suspects in this case,” Murphy said. “The defendants in this case allegedly preyed on the victim’s addictions which resulted in his tragic death. Hopefully, today’s charges will bring some closure to his family. We appreciate the assistance of State’s Attorney Berlin’s office.”

The next court date for Cassata is scheduled for May 26, 2021, for arraignment in front of Judge Jeffrey MacKay. Beulle’s next court appearance is scheduled for May 5, 2021 for arraignment in front of Judge Daniel Guerin.

Members of the public are reminded that these complaints contain only charges and are not proof of the defendants’ guilt. The defendants are presumed innocent and are entitled to a fair trial in which it is the government’s burden to prove their guilt beyond a reasonable doubt.
