Jacob Ben Senior last heard from his daughter, Daniel, on Friday night when the 34-year-old Israeli-American was on her way to the Nova music festival. He hasn’t slept or eaten in days.
“My heart, it's on the floor,” he told CNN’s Erica Hill. “She's everything for me. Without her, there is no value for life.”
Senior is in touch with several other families searching for missing loved ones; they’ve connected on WhatsApp to share information, though there is little to be had.
“We don't know anything. The information, it's zero. That drives you crazy. Nobody talks to you," he said.
Senior said he has not had any contact with the Israeli government or US State Department officials but has opened a case with police. He said he has sent DNA from his daughter's personal items for authorities to use to identify her if needed.
Desperate for any clues, Daniel’s boyfriend returned to the site of the Nova festival this afternoon with a group of others to search the area, Senior said.
“They're going through holes in the ground to caves with trees," he said. "She might be sitting on the tree. She is very strong woman.”
Daniel — a medic —served with the Israel Defense Forces’ Oketz unit, which is a special forces K9 unit, according to her father.
“There is hope in the heart,” Senior said. “There is hope. And we're gonna accept whatever God give us. If it's good or if it's bad. We have to be strong like hell.”
