A State Police helicopter hovered Friday over the home of a mother and teacher who has been missing for almost two weeks.

At the same time, detectives on all-terrain vehicles searched the area near Sylviane Finck Lozada’s house at 2234 Spring-lake Drive.

These were the latest efforts made by law enforcement to find the Brusly High School teacher who has not been seen or heard from since July 11, said Casey Rayborn Hicks, a spokeswoman with the East Baton Rogue Parish Sheriff’s Office.

Sheriff Sid Gautreaux said Tuesday he is “very concerned” for the wellbeing of Lozada, 51.

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

Lozada was reported missing after her family in Belgium was not able to contact her, Hicks said. Lozada kept in regular contact with her family.

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 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.

The Lozadas’ home on Springlake Drive appeared deserted earlier this week, 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.

Hicks said she could not comment further on where the items were found. She also could not comment on what law enforcement was looking for Friday other than to say detectives were doing “due diligence” in looking for clues.

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.
