BUFFALO, N.Y. ( WIVB ) — A man is in custody after an American woman who was declared missing in Budapest was killed earlier this week, Hungarian police said.

Mackenzie Michalski, 31, who had gone to Hungary as a tourist, was last seen at a nightclub on Tuesday, according to a translated announcement released by Budapest police.
