JEFFERSON COUNTY, MO (KTVI) – Family and friends are grieving after a 17 year-old from O’Fallon, Missouri, died at a music festival over the weekend.  It happened at the Morse Mill Hotel in Jefferson County.

According to a witness, paramedics at the scene said Cassandra Patredis likely died of an overdose, but investigators can’t confirm that until toxicology results come back.  Unfortunately, that could take 2 to 3 months.  Until then, devastated friends and family are left to wonder.
The Purge Music Festival was advertised on facebook: a 3-day event at the Morse Mill Hotel with 50 live performances, plus fire spinners, hoop girls, and a twerk contest.
Hotel employee Charles Freese stopped by Saturday’s festival. He said the party was not out of control: “A bunch of energetic youngsters.  It wasn’t my style of music, but they seemed to be having a lot of fun.”
They were having fun until just after 9 that night. Jefferson County Sheriff Glenn Boyer says, “We were called to the scene in reference to an unconscious female, a 17 year-old female. When we got there, there was a large group of about 150-200 people. They had been involved in what we believe to have been a rave party.”
Cassandra Patredis was transported to the hospital, where she later died.
Boyer says the crowd quickly left when officers arrived, and no drugs were recovered at the scene.
But, he says these parties concern him: “It seems like there’s always alcohol involved, and there’s always drugs involved.”
Venue owner Patrick Sheehan says the promoter rented the space from him, and had plenty of safety measures on site, including security guards, sobriety checkpoints, and wristbands.  But none of that saved Cassandra’s life.
Friends say she was a gifted singer and musician.  Her father, Steve Patredis, tells FOX 2 his daughter was happy, bubbly, and loved to joke around.  After attending Fort Zumwalt North High School, she got her GED early.  Her father says she talked about going to college, and becoming a psychologist to help children.
Now the sheriff wants to help teens like Cassandra live long enough to fulfill their dreams.  He says, “If we find out about one of these events, we’re going to be there. We’re going to be there with undercover officers, we’re going to be there with uniformed officers. But in this situation, we weren’t aware that this event was even taking place until we got the call.”
The sheriff says they’re investigating whether the venue had obtained a permit to hold this event. The last time someone died at a Jefferson County party like this was last April, at a rave in a cave near Crystal City.​
