Authorities are continuing their search for a Vicksburg woman reported missing Wednesday from the U.S. Army Corps of Engineers’ mat sinking unit.

Greg Raimondo, Vicksburg District public information officer, said the Corps has sent two survey boats to aid in the search for Larrielle Ross, 20, an employee in the quarters barge galley, who was reported missing Wednesday. The U.S. Coast Guard and the St. Charles Parish Sheriff’s Office are assisting with the search, he said.

“These boats have sonar that allow us to search the river bed,” he said. “We hope Ms. Ross is found alive, and our thoughts and prayers go out to her family.”

Ross, a galley worker on the quarters barge which accompanies the mat sinking unit, was last seen about 2:30 p.m. Tuesday and reported missing when she was not found on the barge about 10 a.m. Wednesday.

The quarters barge is the home for the mat sinking unit’s workers when it is working on the river. It was moored in St. Charles Parish near the Bonne Carre Spillway, Raimondo said. The spillway is west of New Orleans.

“Once she was reported missing, we notified the St. Charles Parish Sheriff and the Coast Guard,” Raimondo said Thursday morning, adding officials did not know if Ross fell from the barge or left it on her own.

He said Ross’ parents, who live in the Kings community, were notified and drove to Louisiana, where they talked with St. Charles Parish authorities.

Ross is a graduate of Warren Central High School and attended Hinds Community College, according to her Facebook page.

He said the Coast Guard is responsible for the river search and the sheriff’s office is heading the investigation in St. Charles Parish.
