In Florida, authorities have identified a second survivor of the February 2018 Parkland mass shooting who died by suicide this month. Sixteen-year-old Calvin Desir took his own life on Saturday, just days after 19-year-old Sydney Aiello also died by suicide. Seventeen students, staff and teachers were killed in Parkland on Valentine’s Day last year, in one of the deadliest school shootings in U.S. history.
