Sheriff Sid Gautreaux said Tuesday he is “very concerned” for the well-being of a mother and teacher who disappeared more than two weeks ago.

East Baton Rouge Parish Sheriff’s Office detectives have not found anyone who has seen or heard from Sylviane Finck Lozada, 51, since about July 11, spokeswoman Casey Rayborn Hicks said.

“With all of the exposure from the media, you would hope that someone would come forward and say they’ve at least seen her,” Hicks said. “At this point, no one has done that. We are concerned.”

Hicks said detectives still have not been able to find any evidence of foul play in Lozada’s disappearance.

Lozada, a teacher at Brusly High School, was reported missing after her family in Belgium was not able to contact her, Hicks said. Lozada kept in regular contact with her family, Hicks said.

Relatives told authorities they last spoke to Lozada on July 11, but investigators are exploring the possibility the date was incorrect, Hicks said. It is possible that Lozada last spoke to her family before July 11, Hicks said.

Lozada’s husband, Oscar Lozada, and daughter traveled to Venezuela on July 9, Hicks said.

Investigators have spoken to the husband, who told detectives he went to Venezuela for medical reasons, Hicks said.

Hicks was unsure where the husband was as of Tuesday afternoon.

The Lozadas’ home at 2234 Springlake Drive appeared deserted late Tuesday, the interior devoid of furniture and belongings.

Hicks said detectives have located the Lozadas’ belongings and were working to establish when the furnishings had been removed and why.

She said she could not comment further on where the items were found.

Gillian Paquet, Lozada’s sister, said Tuesday in a phone interview from her home in Belgium that her family is working non-stop overseas to do anything they can to help find Lozada.

“We don’t know what happened to her,” she said. “It’s terrible. We work all the time to try to find her. We are very, very concerned.”

A fund to help the family with expenses has been set up at American Gateway Bank. Donations may be made to the Sylviane Finck Lozada fund at any bank location or by calling the bank at (225) 387-0011, said Lozada’s friend Karen Wooley.

Wooley said she reported Lozada missing July 18 after she went to Lozada’s home at the family’s request.

Wooley said Lozada’s car was there, but she couldn’t find her friend. That’s when she called authorities.

Authorities found the husband’s car Sunday at the Prairieville home of a family friend whom they did not identify. Hicks said detectives were processing the vehicle for any clues as to Lozada’s whereabouts.

Hicks said detectives were investigating why the husband’s vehicle was at the friend’s house.

Wooley, Lozada’s friend and colleague of 12 years, said Lozada’s daughter is “her world,” which makes the lack of contact that much more uncharacteristic.

“There’s no way she would not try to call her daughter,” she said. “It’s very strange.”

Wooley described Lozada as an intelligent, disciplined and structured person.

“She’s never done anything remotely like this before,” Wooley said.

Lozada is about 5 feet 4 inches tall and weighs 120 pounds. She has brown hair and green eyes.

Anyone with information about Lozada’s whereabouts is asked to contact the Sheriff’s Office at (225) 389-5000 or Crime Stoppers anonymously at (225) 344-7867.
