An Arizona woman is one of four state residents who were recently taken into custody by law enforcement officials after searches of their vehicles. All four face serious drug-trafficking charges that could result in harsh sentences that could mean that they will spend years behind bars if they are convicted.

The 31-year-old woman was driving a Toyota Sequoia on Interstate 19 when she came to an immigration checkpoint, according to a news report.

A drug-sniffing dog was apparently used by officers at the checkpoint, the report stated. The “dog flagged the vehicle” and the SUV was then searched. Law enforcement officers said they found 207 packages of methamphetamine hidden in various compartments in her vehicle, including in doors, floor compartments, quarter panels and in a spare tire.

Officials said they estimated that the meth is valued at approximately $200,000.

In related news, three men were arrested for allegedly transporting varying amounts of meth in their vehicles.

A 19-year-old was arrested after officers found nearly 64 pounds of methamphetamine (worth about $58,000) in his Nissan coupe.

A 28-year-old was arrested after officials found 52 pounds of meth worth approximately $47,000 in his Ford sedan.

Another 19-year-old man was arrested after officers said they found 57 packages containing about $52,000 worth of meth hidden in his Volkswagen sedan.

In all cases, the suspects should decline to speak with prosecutors and investigators until after they have spoken with a criminal defense attorney who understands proper search and seizure procedures, due process and 4th amendment constitutional rights against unreasonable search and seizure.
