FAMILY and friends of missing teenager Jenna Baldwin are clinging to the hope that mystery phone calls they received are from their daughter.

But police remain unconvinced the calls were being made by the 15-year-old, who went missing on September 10.

Jenna's mother Desiree, father Nigel and some of her friends have all received silent phone calls since then.

She has not been seen or made direct contact with anyone since vanishing from her home in Abersychan.

Mrs Baldwin said today: "Everything that has happened so far has been a let down. It seems like all the way through since she's been missing we have had somebody messing around.

"I want to be 100 per cent certain before letting myself think she's OK." The officer leading the investigation, Chief Inspector John Oliver, told the Argus: "The family are not 100 per cent certain. We are not happy it's her until she speaks to her mum, dad or us.

"At the moment, until we get some phone calls from her or a person associated to her we will still carry on with our searches and enquiry."

He added: "These calls just raise everybody's hopes." He added that yesterday afternoon Jenna's mother received a phone call which had a whispering noise on the end.

Jenna's schoolfriends have also made an appeal for Jenna to come home. Her Year 11 friends told the Argus: "We just want to know she's OK." Friend Aislinn Blackmore said they missed Jenna: "She always had time for you. "She would know when you had a problem and would come to you."

Her friends said she loved shopping and was into jeans and make-up. Another friend, Danielle Palmer, added: "She was so funny, when everybody was quiet in lessons she would start singing."

Lauren Tudor described Jenna as a "genuinely nice person" and said her friends were disappointed but not angry that Jenna hasn't contacted them.

She added: "It is really quiet without her, we need her back in RE to make us laugh." Her friends are hoping to hold a Hallowe'en party but say it won't be the same without Jenna.

They have all been looking at photographs and talking about their times with the "bubbly" teenager.

As reported in the Argus, police have now shifted the focus of their hunt for the schoolgirl. Officers have used specialist equipment and helicopters to search areas near where Jenna was last seen.

Anyone with any information about Jenna's disappearance should call the incident room on 01495 232260.
