NEW ORLEANS-- In bayous and ponds across City Park, a team from Houston-based EquuSearch used sonar to try and find missing elementary school teacher Terrilynn Monette.
'We've done searches in New Orleans before and had a lot of success in the water with our sonar equipment,' said Tim Miller, founder of Texas EquuSearch.
Monette was last seen on March 2 outside a Lakeview bar, not far from City Park, which she could have traveled through to go home. Her 2012 black Honda Accord is also missing.
'I think this is part of the process of elimination, in case a vehicle did end up in the water,' Miller said.
EquuSearch has been looking through a number of bodies of water in City Park. They run about six feet deep, with a muddy bottom that a car could sink into. EquuSearch said they have the ability to look through 40 feet of water, and up to 1000 feet of water -- much like they did in the Natalee Holloway case in Aruba.
Still, despite the search, there's been no sign yet of Monette or her car. It comes after a massive search of City Park this past weekend, where 300 volunteers canvassed the area looking for any sign of her.
Monette's mother, Toni Enclade, said she appreciates EquuSearch's efforts.
'I heard that they are very good at what they do,' she said. 'And I hope and pray that they find something, some type of lead or something, to my daughter's disappearance.'
It is an anguish Tim Miller said he understands.
'I've been there before, my own self and know what this family is going through. When I heard mom on TV yesterday crying, how can you help not to help?' he said. 'We'll bring in whatever we've got and leave the results up to God.'
So far, though, results have left many questions and very few answers about what happened to Terrilynn Monette.
