Four suspects, including two 17-year-old boys and a 15-year-old boy, have been arrested and charged with multiple counts of murder stemming from a mass shooting that left three teenagers dead and 15 other people injured at an unsanctioned car show at a park in Las Cruces, New Mexico, police said Sunday.

Students and staff at Florida State University came together for a peaceful vigil to remember the victims of a shooting and to exalt their strong sense of community.
