A volunteer who suffered spinal injuries while trying to rescue a woman who got lost while hiking in Trabuco Canyon with a friend who later admitted to drug possession filed a lawsuit against the woman, his attorney said today. Nick Papageorge was injured in April 2013 while searching for then-18-year-old Kyndall Jack, who went missing along with friend Nic Cendoya while hiking in the Cleveland National Forest. The pair set out on their hike March 31, 2013. Cendoya was found on April 3, while Jack was rescued the next morning.

Cendoya later pleaded guilty to possessing 497 milligrams of methamphetamine that was found in his car in a parking lot.

According to his lawsuit, which was filed June 16, Jack and Cendoya "headed out unprepared and unqualified to a remote and dangerous mountain area with the intent to take hallucinogenic drugs, knowing the likelihood of becoming disoriented, lost and requiring the subject rescue."

The lawsuit contends that Jack created the emergency situation through her own negligence.

"Her willful conduct of placing herself in a recklessly dangerous situation caused the subject injury and devastation to plaintiff," according to the Orange County Superior Court lawsuit.

The lawsuit seeks unspecified damages, but Dubin said Papageorge's has incurred more than $500,000 in medical injuries. "We're hopeful that she has insurance that's applicable and that this can be easily resolved" before going to trial, Dubin told City News Service.
