Hundreds of teenagers in West Orange County have signed a pledge in Krystopher Sansone's memory: A promise not to take drugs.
On Wednesday night, Sansone's mother, Lucy, went to West Orange High School to encourage more kids to sign that pledge during a candlelight vigil in her son's honor.
Narcotics investigators are still trying to figure out what substance five people in their late teens and early 20s ingested inside a Winter Garden home on February 10. All five found were unconscious, and Sansone, 17, died later that morning at the hospital.
It's is something his mother doesn't want another parent to have to go through.
"I have been torn apart," she said. "I just buried my son and laid him to rest Monday."
She said her son was not the stereotypical child anyone would expect this to happen to, adding, "This was a good kid from a good family who made a bad choice that night."
She is very open about her son getting into trouble with marijuana recently, saying he had just finished a drug diversion program three weeks before he died.
"We were told that if he was using something other than marijuana, then we could get him into a residential program. This [marijuana] was all we found in his system."
She said marijuana is a drug that everyone needs to take more seriously. She believes it was the gateway to whatever it was her son ingested that fateful night.
"I know it wasn't just marijuana. I believe it wasn't just marijuana he used that night."
She said investigators will not have her son's autopsy results for another eight to 10 weeks, when they should reveal what the substance was that ultimately took his life.
Krystopher Sansone was set to graduate from high school in May.
