On Monday, her 14th birthday, Catherine Martin left home and headed, her parents thought, to Brock Middle school where she's in Grade 9.

But the girl never showed up in her classes. Her family realized there was trouble when she didn't arrive at home after 3 p.m.

And now their family and that of Catherine's boyfriend, 14-year-old Keenan Warren, are worried. Both teens have not been in contact or showed up for any of their regular activities — school or cadets — since.

Catherine's dad Mike Martin said Wednesday the disappearance is completely out of character for her.

He and his wife Rowena have gone through two days of stomach-wrenching worry and little if any sleep since Catherine didn't come home for her birthday celebration.

His message to her was simple: "Come home, we love you and nothing else matters."

He and his brother have been driving around town looking for the kids while his wife or sister remain at home in case they show up there.

Kamloops RCMP Staff Sgt. Grant Learned put out a public call for help in finding the two on Wednesday morning.

Catherine is described as five foot 10, 120 lbs., slim build, with shoulder-length brown hair and brown eyes. She was spotted Monday night outside a North Shore business wearing a burgundy sweater, acid-wash jeans and a white belt. Her family lives in North Kamloops.

Keenan is described as 5 foot 5, 115 lbs., slim build, with short dark-brown hair, a white zippered sweater, blue jeans, runners and he sometimes wears glasses. His family lives in Juniper.

Both attend cadets together.

Learned said the two could be couch surfing with friends who don't realize family members are worried.

"The parents want to send a message that they are both loved," he said.

"This is out of character for both of them."

He said police don't believe the two, who have been dating about a year, are the victim of foul play.

Anyone with information about Catherine's and Keenan's whereabouts can call the RCMP at 828-3000 or Crimestoppers at 1-222-374-TIPS (8477).
