A St. Tammany Parish Sheriff's deputy has been fired and a Covington woman has been charged in separate investigations into alleged attempts to deliver contraband to parish jail inmates.

The Sheriff's Office says the employment of Deputy Tyson Sonnier was terminated after a bag containing cell phones and containers of tobacco was found July 18 in a vehicle used to transport prisoners to work details.  Sonnier had been assigned to drive the vehicle.  He has not been charged with committing a crime.

In a separate investigation, 26-year-old Porscha Montana of Covington was arrested August 6 for allegedly placing synthetic marijuana at locations where prisoners were scheduled to work.  She was booked into jail on a contraband charge.

The two cases are being treated as separate and distinct as detectives were unable to establish any connection between them.

“The residents of St. Tammany demand and deserve deputies who hold themselves to the very highest moral, ethical and legal standards.  Our agency cannot operate effectively without the public’s complete trust in the men and women who serve them,” said Chief Deputy Brian Trainor.
