“When officers arrived, they found Gauthier’s personal belongings – including her phone – inside and had her car towed to a junkyard,” WAFB reported.
The search was curtailed after a K-9 cadaver dog alerted the same section of the river twice earlier on Saturday, the school said in its statement.
Conditions in the area were unsafe and divers were not deployed, the statement said, but mounted patrol will search an embankment along the river on Sunday and the latest sonar technology will be used on boats by law enforcement officials.
Law enforcement believes no criminal activity or foul play has taken place, based on the evidence gathered, the statement added.
The school’s police have been in contact with Gauthier’s parents, sharing private details with them, LSU said.
Gauthier’s father, Levar Gauthier, joined the search on Friday, and the family held a wake on Friday night near the site where her car was found, WAFB said.
CNN has contacted the Baton Rouge Police Department for more information about the accident and the search.
