PAINCOURTVILLE — An investigation into thefts of a firearm and a $3,000 dirt bike led to the arrests on Thursday of two cousins from Paincourtville, according to an Assumption Parish Sheriff’s Office news release.

Sheriff Mike Waguespack said in the press release that a resident had reported his .40-caliber Smith & Wesson pistol missing on Aug. 18.

The resident noticed the weapon had disappeared from his vehicle shortly after Branden Landry, 24, 6013 La. 1, got out of it, Waguespack said.

The two had met in the parking lot of the Pierre Part library, Waguespack said, because Landry had asked the pistol’s owner for some information about a computer.

Earlier this month, the missing firearm was turned over to the Sheriff’s Office after a Belle Rose man realized the pistol he recently purchased had been stolen.

That buyer told deputies he had bought the Smith & Wesson from Landry, along with a .32-caliber Berretta found to have been reported stolen from Terrebonne Parish.

During the investigation into the stolen Smith & Wesson, Landry told detectives that a cousin, Leadd Lacoste, 20, also of 6013 La. 1, had stolen a 2006 Honda CR 125 dirt bike from the Paincourtville area, and that the two traded the bike for an all-terrain vehicle.

Deputies arrested and booked Lacoste with theft of the motorcycle.

Landry and Lacoste were held in the Assumption Parish Detention Center Friday awaiting bail to be set, deputies said.
