The family of missing Queensland girl Jayde Kendall has made an impassioned plea to anyone who might be responsible for her disappearance.

“Have a bit of human decency,” the 16-year-old’s uncle Craig Morrissey begged during a public plea for information on Monday.

“Just bring her home to us, mate.”

Jayde hasn’t been seen since she was picked up by an 18-year-old friend outside Lockyer District High School, in Gatton west of Brisbane, 10 days ago.

Detective Acting Inspector Matt Howard said police were treating her disappearance as a “suspicious missing persons case” given it was out of character for her to disappear and her bank accounts haven’t been touched.

However, there’s not enough information to suggest she has been murdered.

The car owner has been cooperating with police and remains a person of interest in the case, Insp Howard said.

He said 20 detectives were working on the case and, while searches over the past few days haven’t lead to a breakthrough, about 100 calls to Crime Stoppers were being followed up.

Mr Morrissey said it wasn’t like Jayde to run away but the family was hoping she had because it was the best scenario.

He described his niece as a “really good person” who was committed to her studies and work at McDonald’s.

She wanted to pursue a career in psychology and had just bought a car she had saved up for before she disappeared.

Mr Morrissey said Jayde’s mother passed away several years ago, leaving her to play a motherly role for her little brother.

Her father was too traumatised to speak to media on Monday, he said.

“Jayde is the glue who holds this family together,” Mr Morrissey said.

“Her disappearance has caused untold grief towards us.”
