A missing Louisiana woman's bicycle has been found in a remote, swampy area under a highway bridge in Iberville Parish, about 25 miles from the spot where she was last seen eight days earlier.

Lafayette police spokesman Paul Mouton said Sunday that more than 30 officers searched the area, including a river, for 21-year-old Michaela "Mickey" Shunick, a student at the University of Louisiana.

The Advertiser reported ( http://bit.ly/KVxo15) that search dogs were set to work under the bridge and St. Martin Parish sheriff's deputies rode all-terrain vehicles in the woods, while a Louisiana State Police helicopter flew low over the area.

Shunick, of Lafayette, was last seen about 1:45 a.m. on May 19, when she left a friend's house to go home. A video taken about that time showed her and, separately, a late-model, white, four-door pickup truck.
