Friends and family have set up a reward fund for information that may help locate a 21 year old UW Green Bay student, missing since a night of partying and bowling last Friday. Melissa Sinitsky is Mahalia Xiong's sister. She says somebody must have seen Mahalia if she stopped at a gas station or store, and she hopes the reward prompts them to call police. Sinitsky says if people want to help, they can donate to the reward fund at Pioneer Credit Union. In Green Bay. Green Bay Police are treating the disappearance as a suspicious case, because Xiong's family says it's unlike her to go so long without contacting them.
