Portugal reacts to citizens' connections to shootings in US

This week saw two shootings in the US that made national and international headlines. The first was at Brown University in Providence, Rhode Island. Two days later, Nuno Loureiro, a Portuguese immigrant and a professor at the Massachusetts Institute of Technology, was found shot dead at his home in Brookline, Massachusetts. A suspect in both shootings was found dead in a New Hampshire storage facility. He was a former student at Brown and also a Portuguese citizen. It's a developing story and being watched closely in Portugal, as journalist Sofia Neves, a reporter at the Portuguese daily paper PUBLICO, tells The World's Host Carolyn Beeler.
