No one has heard from Catie Miller in nearly two weeks, and her family is growing increasingly concerned.

Monday was critical as they hoped their daughter would show up for an important appointment.

But the day has come and gone, and hope is leading to desperation.

Catherine Miller received a scholarship to Dalhousie University.

She was on the Dean’s List at Saint Mary’s and graduated from NSCC as an electrician.

“At first we were all in disbelief,” explains Catie’s father John Miller. “As the hours and the days ticked by, we went through some despair.”

No one has heard from the Dartmouth woman in nearly two weeks.

Her parents say even when they are not with her, they’re usually always in touch through texting or social media.

“It’s a nightmare, it’s a nightmare,” exclaims Catie’s mother Terry Miller. “You go to bed at night wondering if she’s dead or alive, who’s got her or if she’s been kidnapped.”

The family was holding out hope until Monday.

Catie had a very important appointment related to her 3-year-old son, Oliver.

“This morning when I was waiting to find out if she kept that appointment my heart was in my throat,” says John Miller. “It’s hard to explain. It’s hard to explain.”

Her parents say she’s been struggling to find work since graduating last year, and they think that has contributed to depression she’s experienced.

But they say they have no idea where she could be, and neither do police.

“At this time, we don’t have any information to lead us to believe that she’s met with foul play,” explains Constable Tracy MacDonald of Halifax Regional Police.

Catie’s father says someone, somewhere must know something.

“I think most people would put the loss of a child at the top of a parents’ worst fear,” he adds. “I think maybe a missing child is worse than that because you just don’t know.”

Incase Catie may have internet access; her parents have a message for her.

“You know how much we love you, and how much we miss you,” exclaims her mother. “You just have to come home to us, and Oliver misses his mommy. Please!”

A desperate plea, from parents who simply want to know their daughter is safe.
