Florida State University student Robbie Alhadeff has now been deeply affected by two Florida school shootings. Alhadeff lost his 14-year-old sister, Alyssa, in the 2018 Parkland High School massacre where she was one of 17 people fatally shot. Alhadeff and his sister, a freshman soccer player, were very close, he told ABC News Friday. He said a friend texted him about gunfire at FSU while he was walking to his apartment Thursday, “I ran right back into my apartment because I was scared about the whole situation,” he said. Alhadeff, who took two weeks off from school after his sister was killed, said his friends are “terrified” to return to class at FSU after the most recent shooting there. “A lot of the people I’m friends with are from Parkland and a lot them go to FSU,” he said. “This is the second time it’s happened — and no one I know wants to go back to school.” “You could end up being killed just going to learn,” he added. “I thought this would never happen again,” Alhadeff said, “but it continuously keeps happening — and something has to change.” The fathers of two students killed at Parkland told ABC News that they are not necessarily shocked about the latest shooting. Manuel Oliver, whose 17-year-old son, Joaquin, was killed in Parkland, said: “I don’t understand how anyone could be surprised” by another school shooting “if we haven’t done anything to stop it.” “We will continue to fight — these kinds of events empower us to do more, different things, because whatever we’ve been trying is not enough,” said Oliver, who has become an advocate for gun control. Fred Guttenberg, whose 14-year-old daughter, Jaime, was killed in Parkland, said some of Jaime’s former classmates were at the FSU student union when the gunfire broke out. “As a father, all I ever wanted after the Parkland shooting was to help our children be safe,” Guttenberg, who has become a gun reform supporter, wrote on social media. “Sadly, because of the many people who refuse to do the right things about reducing gun violence, I am not surprised by what happened today.” Phoenix Ikner, the 20-year-old suspected of killing two people and wounding five, was shot by officers. A motive is not known. The five injured victims are all expected to survive, as is the suspect, hospital officials said.
