Teen may have met someone on Valentine's Day before vanishing
From the article
Police say the teenager had confided in friends that she was unhappy with a relationship she was in.
Det Ch Insp Howard said: "One of the real lines of enquiry is around trying to understand Leah as a person and what was going on in her life at the time.
"We have identified that she was telling friends that she had a number of stress factors and things going on that were causing her anxiety and upset.
"There was a number of things going on, not one particular thing really stands out.
"But it is evident that there was a relationship that Leah was involved in that was not turning out or developing the way Leah hoped it would have done.
"So there clearly were some factors going on in Leah's life at that time."
