A Louisiana woman said the driver of a truck seen in surveillance video in the case of a missing Lafayette woman had tried to pick her up two months ago. Michaela \"Mickey\" Shunick was last seen riding her bike home from a friend\'s house about 2 a.m. May 19. Police released surveillance footage of Shunick, 22, riding her bike on the night of her disappearance as a white pickup truck drove by going the opposite direction, The Daily Advertiser of Lafayette reported. Two other vehicles in the footage might be involved in the woman\'s disappearance, police said. Tasha Patterson, of Lafayette, said a middle-aged white man driving the white truck approached her two months ago and offered her a ride and asked her to have sex with him for money, ABC News reported Monday. \"He says he rides around town all the time trying to pick up pretty girls,\" Patterson told ABC News affiliate KATC-TV, Lafayette. Police found Shunick\'s bike Sunday beneath a bridge near the Atchafalaya River, more than 27 miles from where she was last seen leaving her friend\'s home. Investigators have found no other signs of the woman in the vicinity. \"We\'ve expanded as wide as what we feel comfortable that we don\'t miss anything,\" Officer Paul Mouton of the Lafayette police department said. \"It is quite a large area down beneath the bridge.\"
