A tug boat captain pulled two people from the Intracoastal Waterway Sunday night after the pair jumped into the water while fleeing from deputies who discovered their mobile methamphetamine lab, authorities said.

Kevin Landry, 32, and Melissa Tanner, 45, were arrested after a daylong flight that began with a deputy checking on a report of a suspicious car parked beneath the La. 317 Intracoastal Bridge, according to the St. Mary Parish Sheriff’s Office arrest report. They were booked on warrants on operating a clandestine laboratory, simple burglary and unauthorized entry of an inhabited dwelling.

In conducting the check around 8 a.m., the deputy saw the car speed away before he later located it unoccupied on a nearby levee with an active meth lab in the passenger seat, the Sheriff’s Office said. Items in the car identified Landry and Tanner, and footprints near the scene led to the bayou. The Sheriff’s Office later received reports two people had entered onto a business’s property and had tried to trespass at a private camp.

The tug boat captain alerted authorities he had pulled two people from the water around 8 p.m. and brought them to the Calumet boat landing, where Landry and Tanner, no address given, were taken into custody. No bail has been set yet.
