An American teenager and two other people were killed in an avalanche near the popular Swiss resort of Zermatt on Tuesday. One person was flown to the hospital with serious injuries. The avalanche occurred around 2 p.m. on Monday in an off-piste area of Riffelberg, above the resort and below the famous Matterhorn peak. Rescuers recovered three bodies and the injured 20-year-old Swiss man. The victims were a 15-year-old American boy, as well as a man and a woman whose identification has not yet been concluded, police in Valais canton said in a statement. They provided no further details, but said they currently have no information on the woman’s identity. Prosecutors were investigating the incident. Last month, five members of a Swiss family were found dead after going missing while cross-country skiing near the Matterhorn in difficult conditions. Authorities abandoned the search for a sixth missing person days later.
