Our hiking group had reached the highest point of our trek through the Andes to Machu Picchu. Now our guide was leading us in a Quechua ritual. We took turns placing stones in an "apacheta" pyramid over herbs and bits of chocolate bars, offering them to Apu Salkantay, the spirit of the mountain sacred to the Incas. Its ice-covered peak shone above us, spotlit by the sun.
The 20-year-old man suspected of killing five people with a rifle at a Macy's makeup counter had a string of run-ins with the law in recent years, including charges he assaulted his stepfather, and was described by a neighbor as so "creepy, rude and obnoxious" that she kept a Taser by her front door.
