Mahnomen Woman Charged With Drug-Related DWI

MAHNOMEN, Minnesota (trfnews.i234.me) — Heather Quinn Deegan faces two impaired driving charges in Mahnomen County District Court.

The charges followed an incident outside Dollar General on May 24, 2026.

According to the criminal complaint, White Earth police responded around 7:50 p.m.

The report involved several people who appeared unconscious inside a parked white Buick Enclave.

Police first arrested Brandin Quinn English Jr., formerly known as Brandin Quinn Deegan, on suspicion of impaired driving.

Officers then told the remaining passengers that only a valid licensed driver could move the vehicle.

The complaint says Deegan was told her license was revoked.

Police also warned her several times that she could not legally drive the SUV.

Alleged Vehicle Movement

Despite those warnings, Deegan allegedly entered the driver’s seat and started the vehicle.

The complaint says she placed the SUV in drive and began moving it.

Police immediately ordered her to stop.

Deegan reportedly said she only intended to reposition the vehicle.

Officers then asked her to exit and began an impaired driving investigation.

The complaint says officers noticed uncontrolled hand and facial movements while speaking with Deegan.

Police also reported glossy eyes and difficulty following instructions during an eye movement test.

During a walk-and-turn test, Deegan allegedly used her arms for balance.

She also missed several heel-to-toe steps and completed an improper turn.

During a one-leg stand, Deegan allegedly lowered her foot and used her arms for balance.

The complaint also describes facial and eyelid tremors during another sobriety test.

Police said Deegan estimated 30 seconds had passed after about 24 seconds.

Prosecutors charged Deegan with third-degree DWI involving a controlled substance.

That charge is a gross misdemeanor carrying up to one year in jail.

It also carries a possible fine of up to $3,000.

The complaint lists a March 2026 impaired driving incident as an aggravating factor.

Deegan also faces fourth-degree DWI involving a controlled substance.

That misdemeanor carries up to 90 days in jail and a possible $1,000 fine.

A judge approved a search warrant for a urine sample, according to the complaint.

The sample was submitted for chemical testing.

Deegan is presumed innocent unless proven guilty beyond a reasonable doubt.
