SEDONA, Ariz. (AP) — Two teenage girls from outside the United States were among four people who died in a northern Arizona plane crash.

The Yavapai County Sheriff’s Office identified them Thursday as 18-year-old Johanna Naber, of Shellbrook, Saskatchewan, and 19-year-old Sabrina Giebelen, of Krefeld, Germany.

Also killed were 22-year-old Jonathan McGeary, of Flagstaff, and 23-year-old Levi Wallace, of Prescott.

McGeary was flying a single-engine Cessna that crashed Sunday in a remote canyon near Sedona. His father, Dennis, says the four who met through Christian youth camps had planned to sightsee and have lunch in Sedona that day.

The National Transportation Safety Board is investigating the cause of the crash.
