Ido, the brother of Ariel Tzafrir who died at a nature party in the Negev, said in conversation with Galei Tzahal, "We went to this party together, I asked him if he wanted to come back with me and he refused. He told me he loved me, I told him to call when he left. I didn't hear from him again.
"From what I understood from what happened there after I left, he probably accidentally drank from the wrong bottle. For all their life they teach children not to touch these substances, but they don't teach them what happens when they do touch them. No one knew how to take care of him."
