Officials have released the 911 call that was made the night a group of teens overdosed on unknown drugs.

Investigators don't know what the five young Orange County residents overdosed on that killed one of them and hospitalized the others.

The 911 call, which was made by a resident living at the home, sheds light on what was happening just before the teens were rushed to the hospital. The caller said she was awakened by commotion coming from the kitchen.

"I heard banging in the kitchen so I went out there to check what was going on. They were like staring at the ceiling and I'm like whats going on, what are you guys doing, and they're not answering me and going crazy," the caller told a dispatcher.

"I think they're on drugs or something," the caller also said.

According to investigators, 17-year-old Krystopher Sansone died at the hospital shortly after paramedics were called to the home in the Four Corners area of Orange County.

Sansone's family and other residents in the neighborhood said they think the group overdosed on synthetic street drugs, typically made of toxic chemicals that are constantly evolving.

Sansone's parents told WFTV they want to raise awareness about the dangers of synthetic drugs.

"I want kids to take a stand and say enough is enough, not one more family, not one more child," Lucy Sansone said.

Investigators said they won't know what substance the group overdosed on until toxicology tests are complete. Sansone's parents just want to know what took the life of their son.

"We are looking for justice, we are looking for answers," Sansone said.
