A teenager died and four others were seriously hurt early Sunday morning after overdosing on an unknown substance, Orange County sheriff's deputies said.
Deputies were called to a home at 14308 Vista Del Lago Blvd. in the Four Corners area of Orange County around 3 a.m. Sunday.
Deputies said when they arrived, they found five people unconscious after overdosing on a substance.
Late Sunday, deputies confirmed 17-year-old Krystopher Sansone died as a result of the overdose. One other teen was released from the hospital and three others remain in stable condition.
Deputies said the patients' ages range from late teens to early 20s.
Friends of the teens say the group may have been partying while the homeowner was away on vacation. They also said the group may have ingested the drug commonly referred to as bath salts.
Orange County sheriff's drug enforcement unit is investigating and will be working to determine if criminal charges will be filed.
