BOISE, Idaho — An 18-year-old man planned to attack churches in a northern Idaho city using a metal pipe, butane fuel, a machete and, if he could get them, his father's guns, according to federal prosecutors who charged him with attempting to provide material support to the Islamic State group.
Authorities said Alexander Scott Mercurio adopted the Muslim faith against his Christian parents' wishes and was in contact with FBI informants posing as Islamic State group supporters.
