Police, the FBI, volunteers and family members say they\'ve been searching for a 22-year-old Lafayette, La., woman missing since early Saturday. Police said Michaela \"Mickey\" Shunick, a senior anthropology major at the University of Louisiana-Lafayette, was last seen riding a bike home from a friend\'s house about 2 a.m. Saturday, ABC News reported. Family members held a candlelight vigil Tuesday night, announced a reward of $20,000 for tips leading to Shunick\'s whereabouts and handed out flyers. Her sister Charlene told ABC affiliate KATC-TV, Lafayette, she\'s hopeful Shunick will be found. \"I think she\'s OK. I think she\'s alive. I think she\'s out there,\" Charlene said. Shunick\'s parents said she had always carried Mace while riding her bike to protect herself. Police said they\'re searching a wide area. \"It\'s a very wide scope for us to look at,\" Cpl. Paul Mouton said. \"We\'re canvassing and checking a lot of different businesses for video evidence.\" Shunick stands about 5-foot-1 and weighs 115 pounds. She was last seen wearing a multi-colored striped pastel shirt, jeans and gray shoes. Members of her family say they can\'t think of any reason anyone would want to harm her.
