Tangipahoa deputies seized approximately $800,000 during a Tuesday night traffic stop on Interstate 12, the Sheriff’s Office has announced.

Sgt. Tommy Ferrand was using a radar gun on the side of the highway near Robert about 11 p.m. when he clocked a speeding Ford F-150 truck and pulled over the driver, 41-year-old Frederick Brown, of Houston, according to a news release.

Brown said he had been working in Mississippi, but his wife and passenger Tigress Brown, 38, told Ferrand a conflicting story about their time there, the release states.

Ferrand asked to search the vehicle but was denied. A sheriff’s K-9, Mako, sniffed around the truck and indicated it smelled drugs, authorities wrote. Deputies searched the vehicle and found about $800,00 in cash but no drugs, spokeswoman Dawn Panepinto said.

According to booking logs, the Browns were booked into the parish jail Wednesday but released the same day into the custody of federal marshals.

The case has been turned over to the Drug Enforcement Administration. DEA Special Agent Debbie Webber said the Browns face one count each of conspiracy with intent to distribute cocaine.
