(CNN) -- Police seeking a missing Fort Bragg soldier Thursday concluded their search of a pond northeast of Fayetteville, North Carolina, saying no new leads were developed from the effort.
A lead in the case of Pfc. Kelli Bordeaux led to the deployment of a dive team in nearby Eastover, said spokesman Gavin MacRoberts of the Fayetteville Police Department.
Police Chief Tom Bergamine told reporters Thursday afternoon that investigators will continue talking with those who were at a Fayetteville bar where Bordeaux was last seen early Saturday. He would not talk about whether anybody traveled with Bordeaux to the club.
"We are still doing additional interviews and nothing new has developed," the chief said.
The disappearance remained a missing-person case.
"It's very uncharacteristic (of Bordeaux) and that's why we have grave concerns," Bergamine said.
Detectives have spoken with one of the last people known to have contact with Bordeaux, the chief said. That person is a convicted sex offender.
The soldier, 23, left the Froggy Bottoms bar early Saturday, police have said. The GI had been drinking and was given a ride home by a bar employee, according to a U.S. Army official who spoke on condition of anonymity.
At some point, the Army official said, Bordeaux sent two text messages. One said, "Got home safely." The official did not know who the text was sent to or the contents of the second text message.
Authorities have talked with "numerous individuals" as part of the investigation into Bordeaux's disappearance, Bergamine said. They include Bordeaux's husband, who did not accompany her to the bar, he said. Officers believe the husband was not in town at the time of his wife's disappearance.
Bordeaux's older sister, Olivia Cox, told reporters Tuesday it was out of character for Bordeaux to miss work.
Bordeaux's mother, Johnna Henson, said police had told her that an individual gave her daughter a ride to the bar, where she took part in karaoke. Henson told HLN's Jane Velez-Mitchell on Tuesday that her daughter was "spooked" while someone was driving her home, and that Bordeaux reportedly told the driver to let her out before she reached her apartment. Henson said she does not believe her daughter arrived home.
Bordeaux is described as being 5 feet tall and weighing 99 pounds, with blond hair and brown eyes. She was last seen wearing black shorts and a pink halter top, police said. Bordeaux lives off base, according to Jackie Thomas, Fort Bragg spokeswoman.
A health service specialist, Bordeaux is assigned to the 601st Area Support Medical Company, 261st Multifunctional Medical Battalion, 44th Medical Brigade.
Police asked anyone with information to contact Fayetteville police through a hotline.
