A Minnesota woman recently celebrated her 10th year of sobriety by meeting up with a state trooper with whom she has developed a unique and special relationship.

Amy Martin was pulled over 10 years ago for driving erratically down Highway 77 near Bloomington.

Minnesota State Trooper Kristie Sue Hathaway, new to the force, noticed Martin had been drinking.

“I went up and could see that she had watery, glassy eyes,” the trooper recalled to local NBC affiliate KARE.

She also found an open bottle of vodka in the center console of Martin’s SUV.

Martin’s daughter, Madeline, around 2 years old, was in the backseat.

Since that day, Martin promised to sober up. She credited Hathaway with saving her life.

“If this wouldn’t have happened, there is no question in my mind, I would not be here today. She saved my life,” Martin told reporters.

After the arrest, Martin’s parents were called to pick up Madeline, while Martin rode with Hathaway to the Hennepin County Jail.

Hathaway remembered what she told Martin before she was booked at the jail.

“I remember saying right before you got booked in, ‘Please don’t do this to your daughter. She needs a mom. I know because my mom left when I was 10.’”

Hathaway told Martin that she was raised by her aunt and uncle because both of her parents struggled with alcohol abuse.

Martin promised Hathaway she would change her ways, but the trooper was initially skeptical as it was already her second DWI arrest.

“Quite frankly, she had said it and I was like, ‘OK, well…’” Hathaway said. “I didn’t think that I’d hear from her.”

A year later, Martin surprised Hathaway by showing up to her work with a one-year sobriety medallion.

Every year since, Martin has repeatedly given Hathaway her yearly awarded medallion.

Hathaway for her part has held onto each of Martin’s medallions at work. She said it inspires her to stay on the force.

“It’s been a really tough couple years in our field. There have been times when you kind of wonder like, ‘Why am I in this job?’” Hathaway said. “It reminds me of why. It gives me hope.”

The two have also kindled a strong friendship, with Martin cheering Hathaway on during the Twin Cities Marathon and the pair attending each other’s weddings.

Madeline, now 12, is proud of her mom.

“I’m glad she made the choice to do what she did and make a promise that she would do it and actually accomplish it,” she said.
