(CBS/KLFY) LAFAYETTE, La. - Police in Louisiana say they are now searching for a 21-year-old college student who went missing after leaving a friend's residence early Saturday.

Michaela "Mickey" Shunick was last seen riding a bicycle around 2:00 a.m. on May 19, 2012, according to a Lafayette Police Department press release.

Shunick's family says they knew something was wrong Saturday morning when she didn't attend her brother's graduation ceremony, reports CBS affiliate KLFY.

According to the Daily Advertiser, the FBI joined local and state police in the search on Monday, which was also Shunick's birthday.

"We just want her to come home," Michaela's sister Charlie Shunick told the Daily Advertiser. "Anything -- any clue -- if anyone saw her."

The 21-year-old is reportedly a senior anthropology major at the University of Louisiana at Lafayette.

Police say Shunick is a 5'1" white female, with blonde hair and weights 115 pounds. She was last seen wearing a pastel, multi-colored striped shirt, light wash skinny jeans and grey shoes. Shunick departed the residence on a black Schwinn bicycle with gold handle bar grips and wearing a brown leather backpack purse. It is believed that she was going to her residence near the intersection of Ambassador Caffery Parkway and Congress Street in Lafayette.

Detectives are asking anyone with any information about the case to contact the Lafayette Police Department or Crime Stoppers at 232-TIPS.

A $10,000 reward is being offered for any information that may lead to finding her.
