The parents of a missing police officer are making a public plea for information as police investigate her disappearance.

Catherine Campbell is a constable with the Truro Police Service but her parents say she lives in Dartmouth and commutes to work.

The 36-year-old is originally from Stellarton, N.S. and had been commuting from Pictou County to Truro, until she moved to Dartmouth three and a half months ago.

Her father, Stellarton Fire Chief Dwight Campbell, says she was last seen on surveillance video entering her Windmill Road apartment around 6:30 a.m. Thursday.

He says she had just finished her shift, and that he spoke to her later that day, but that there was nothing unusual about their conversation.

Dwight says she was reported missing when she failed to show up for her shift Monday morning.

“When she didn’t show up for work Monday morning, the Truro police called Halifax police to come over and check and see if she slept in because she’s never late for work,” he says.

“We just don’t know where she went or what happened. We’re just waiting for the police to do their investigation and see what happens when they finish their investigation.”

Campbell’s parents say she isn’t in a relationship and is very dedicated to her work. They also say it’s out of character for her to leave without telling anyone.

“It’s very out of character for Catherine … for anything like this to happen,” says her mother, Susan Campbell. “She’s very dedicated to her work and she’s a very outgoing person, so she’d never leave anybody like us feeling this way.”

Campbell has been with the Truro police service since 2009. Police say the fact that Campbell is an officer is not a factor in the investigation.

“The process is the same,” says Halifax Regional Police Const. Stacey Opalka. “We treat every case, missing person's case the same.”

Police say Campbell’s car is accounted for and there is no information to suggest she has met with foul play, but they are concerned for her well-being.

“The cause of concern in this particular missing persons case is it’s out of character for Miss Campbell,” says Opalka. “She is a very scheduled person and it is uncharacteristic of her, so it is cause for concern.”

Campbell is described as a white woman with a medium build, blonde hair and blue eyes.

Her parents are asking anyone with information about her disappearance to contact police.

“If anyone out there has any information, has seen her, please call the police. And if she can hear this, call home,” says her mother.

“We just want to know where she is and we want her home.”
