Stearns County woman pleads guilty to methamphetamine charges in Polk County – Grand Forks Herald

POLK COUNTY, Minn. — A Sartell, Minnesota woman pleaded guilty to selling methamphetamine and driving under the influence in Polk County on Monday, Oct. 28.

Sonja Robin Plantz, 42, pleaded guilty to first-degree misdemeanor sale of at least 17 grams of methamphetamine within 90 days and fourth-degree misdemeanor driving while under the influence of a controlled substance.

The crime carries a maximum sentence of 30 years in prison, but Minnesota’s sentencing guidelines recommend between 56 and 150 months.

An additional first-degree count, which carries an enhanced penalty due to a prior drug-related conviction, is also expected to be dismissed.

The proposed plea agreement states that the state will seek the minimum prison sentence and the defense will be free to waive it.

Plantz stepped aside

Because of his demeanor and the way he answered questions — with vague and inconsistent answers — the officer suspected he was involved in criminal activity, according to a probable cause affidavit filed in March and in the case.

A K-9 detected the odor of a controlled substance; Plantz allegedly admitted to having methamphetamine in his vehicle that morning and using it. A drug test later confirmed this.

His vehicle was searched and law enforcement found a bag of suspected methamphetamine, the statement said. The bag was field tested and showed a positive result. It weighed 3.8 grams.

Plantz told law enforcement that he agreed to sell one ounce of methamphetamine to someone in Polk County for $600, the statement said. Plantz was returning from selling methamphetamine at Winger when he was pulled over.

He said he bought three ounces from someone in Monticello, Minnesota, the day before and sold two ounces to a man at a rest stop near Clearwater.

Sentencing is scheduled for 9 a.m. on Feb. 6.
