Louisiana authorities say they have been "flooded" with tips in their search for a missing college student last seen leaving a late-night party by bicycle.

The search for Michaela "Mickey" Shunick intensified after police released surveillance videos Friday showing a bicyclist thought to be the missing 22-year-old college student. Police also said they were eyeing a white four-door pickup truck seen in the same video.

"We've actually been flooded with information on potential trucks and why they are suspicious, that we should check a residence because there is a truck there," Lafayette police spokesman Cpl. Paul Mouton told the Daily Advertiser. "The tips have included anything and everything. It's been a tremendous response.

Shunick was last seen around 2 a.m. May 19 leaving a house party in a neighborhood popular with college students. The anthropology major at the University of Louisiana, who friends describe as "responsible," left the home on a black bicycle.

"The first thing that raised a flag for us is when she didn't show up to her brother's high school graduation," Ashley Says, a close friend of Shunick told Fox44.

"She's not a rebel. She always has a can of mace in her front pocket, she obeys all traffic laws.She loved to have fun, but she's really responsible," Says told Fox44.

Shunick's friends have organized search parties and are sharing her story on social media, desperate for clues.

"She loves life," Says told Fox44. "She's a great person, and we’re all just trying to keep positive thoughts."

Shunick is white, with blond hair and about 5-foot-1 and 115 pounds. Anyone with information is asked to call 337-291-8633.
