Two teenagers have been arrested following a medical emergency at an overnight graduation celebration in Prosper that left several high school seniors sick and sent eight of them to the hospital. Authorities believe the incident may be linked to drug-laced edibles distributed at the party.
Arrests Made in Ongoing Investigation
On Wednesday, Prosper Police announced the arrest of 17-year-old Kyle Muchineuta from Prosper and 18-year-old Cesar Omana from Frisco. Both are facing charges of manufacture and delivery of a controlled substance—a first-degree felony under Texas law. The two teens were taken into custody without resistance and are currently being held at the Collin County Jail.
While authorities have not officially confirmed the substance involved, speculation among parents and attendees points to THC-infused gummies being a possible cause. The police have not released toxicology results or identified the specific substance, citing the ongoing nature of the investigation.
Graduation Celebration Turns Dangerous
The incident took place during a traditional graduation party known as “Graduation Celebration,” a parent-led, drug- and alcohol-free event for seniors from the three high schools within Prosper Independent School District (PISD). Held annually at an off-campus venue, this year’s event occurred at 3R’s Ranch, located at 1695 North Coit Road.
Students were checked in at Prosper High School before being transported to the venue for the all-night lock-in. However, what was meant to be a safe and festive send-off for seniors turned chaotic in the early morning hours.
Emergency Response Mobilized
At approximately 2:15 a.m. on Saturday, May 17, Prosper ISD Police called for emergency assistance after multiple students began showing signs of medical distress. First responders from Prosper, Frisco, and Celina arrived quickly on scene. Paramedics treated several teens and transported eight to area hospitals for further care.
A statement from the Town of Prosper confirmed the emergency and praised the rapid response by local emergency services. “Paramedics from Prosper, Celina, and Frisco treated multiple individuals experiencing medical distress and transported 8 patients to local hospitals,” the statement read. “The Prosper Police Department is conducting an ongoing investigation into the matter. Due to the ongoing nature of this investigation, we can offer no further information at this time.”
School District Responds to Community Concerns
Although the event was organized independently by parents, PISD acknowledged the incident in a message shared with families. “While we cannot provide specific details, several young adults experienced medical emergencies and required transport from the event. The Town of Prosper responded quickly, and Graduation Celebration ended early,” the statement read. The district emphasized that it did not host or oversee the event, nor was it held on school property.
Parents Demand Answers
As rumors circulate, concerned parents are demanding transparency. One parent, identified only as Thomas, expressed frustration over the lack of clarity. “They’re saying it’s a medical emergency, but what is it? We don’t know what our kids took and nobody is giving us answers,” he said. “We’re hearing from other people that they took like an edible gummy. I’m guessing that’s what it was, and we’re just trying to figure out what happened.”
Looking Ahead
The Prosper Police Department continues its investigation into the source and distribution of the suspected substance. Officials urge anyone with information to come forward. Meanwhile, students affected by the incident are reportedly receiving appropriate medical treatment.
As the community reels from the unsettling turn of events, the focus remains on uncovering the truth and ensuring the safety of future school-sponsored and parent-organized events.
