Authorities in Puerto Rico are investigating the fatal shooting of three people in a central mountain town in the U.S. territory. Police said Wednesday that those killed include a 16-year-old boy found dead in a car with the other victims, one of whom later died at the hospital. Police said a 19-year-old that was part of the group survived the shooting and was airlifted to the hospital, AP reported. It is unclear what led to the shooting. No one has been arrested in the killings, which occurred Tuesday in the town of Cayey.
