The parents of Krystal Muhieddine, Wally and Suzanne, speak to the press on Thursday. Credit:Danielle Smith Mrs Muhieddine last saw her daughter at 5.30am on Tuesday, sitting in the passenger seat of a silver hatchback with red P-plates as it sped off from outside their house in Mount Street, Hunters Hill. "Someone was waiting for her. She’s never dated anyone. She’s never had a boyfriend. She’s never been anywhere without me dropping her off. "We’re pretty distressed. We haven’t been able to make contact with her." Krystal’s mobile phone has been switched off and the family said they had been checking her emails regularly for any clues.

Missing since Tuesday morning: Krystal Muhieddine. At a press conference, Mrs Muhieddine was at times overcome with emotion as she made a plea to Krystal to come home. ‘‘You’ve done nothing wrong. Just come home. It’s nothing we can’t fix.’’ Krystal’s father, Wally Muhieddine, said they knew Krystal has been communicating with someone online. He said Krystal’s friends ‘‘believe she’s spoken about a boy but we don’t have anything else beyond that’’. ‘‘She’s only a baby. She slept with a teddy bear,’’ he said. ‘‘She’s never been anywhere on her own. It’s the first time in her life that ... we don’t know where she is. But if you’re with Krystal you need to understand she’s just a baby, she’s not an adult. She’s tall but she’s actually a baby and you need to call us and bring her home safely.’’

Mrs Muhieddine said there was no conflict at home and that Krystal came "from a stable environment". The last confrontation she had with Krystal was on Friday night, when the teenager lied to her sisters that she have been given permission to go to the cinema to watch The Hunger Games with a school friend. Mrs Muhieddine said she reprimanded her daughter afterwards for not telling her where she was going and confiscated her phone. She said the family then "had a great weekend". Mrs Muhieddine believes Krystal may have met the person with whom she ran away that night.

She said that she and her husband did not allow social media in the house, but she believes Krystal was using the smartphone messaging app Kik to communicate with the person she left with. She said there was no indication that Krystal was unhappy and that her daughter had "got over" the bullying experiences from her previous school. Krystal enrolled in year 8 at Santa Sabina College, Strathfield, seven weeks ago after leaving her old school. "She had a lot of bullying issues. She didn’t keep any friends at [her previous school]. She’s just didn’t fit in with the clique there. "She’s so happy ... we thought she had turned a corner."

Mrs Muhieddine said teachers at the new school had become just "like a second family" and were giving herself, her husband and three other daughters a lot of support. Krystal is the second youngest daughter of the family. Mrs Muhieddine said her daughter stopped playing sport a year ago because a growth spurt "caused a problem with her knees". Krystal is close to 180 centimetres tall. "It’s very devastating. Her sisters have just gone out to hand out leaflets at the shopping centre in the hope someone recognises her," Mrs Muhieddine said. "We don’t know what to do."

A family friend, who asked to remain anonymous, said she had known Krystal since the girl was seven. "She was a performer. The first present we gave her was a magic set," she said. "She’s a very vibrant little girl. I suspect she’s strong willed. She’s normal adolescent. "I’m concerned that the person who picked her up ... that she may be preyed upon." Inspector Richard Puffett, from Ryde Local Area Command, said detectives would be following up more information on Thursday and talking to "potential persons" who might know where Krystal is.

Krystal has a thin build, shoulder length brown curly hair, black framed reading glasses and was wearing a dark navy blue hooded top, police said. She is believed to have taken a green school bag with her, containing a small amount of cash and clothing. Inspector Richard Puffet from Ryde Local Area Command said running away was ‘‘totally out of character’’ for Krystal and urged her to call her parents or contact Crime Stoppers. Anyone who sees Krystal or has information is also asked to phone Crime Stoppers on 1800 333 000.
