SAPPORO - A zookeeper on the northern main island of Hokkaido was served a fresh arrest warrant Friday for allegedly killing his wife before disposing of her body in a zoo incinerator, according to police.

Tatsuya Suzuki, 33, is suspected of murdering his wife Yui, 33, at their house in Asahikawa, Hokkaido, on March 31. He has admitted to the allegation, telling the police that he strangled her with a rope because he had become "frustrated" by her demands.
