WHAKATANE, New Zealand (AP) — New Zealand police said Tuesday they were opening a criminal investigation into the deaths of tourists on a volcanic island. Five deaths were confirmed after Monday’s eruption of the White Island volcano. Eight other people are feared dead, but unstable conditions on the island are hindering a search. About 47 people were on the island at the time, and some of those evacuated suffered critical burns. Unstable conditions continued to hamper rescue workers from searching for at least eight people missing and feared dead after the volcano off the New Zealand coast erupted in a towering blast of ash and scalding steam while dozens of tourists explored its moon-like surface.
