'They are a good family and had just had a baby girl. There were a lot of children - but they seemed to cope fine. They were always looking out for their children
'I spoke to them after Bernadette went missing to wish them all the best and they were really gutted about it.
'I messaged her when the news came out about a suspect man being arrested and she said she had just come back from giving a statement to police. I just told her that I hoped everything goes well.'
DCI Jerry Waite said: 'Due to the length of time Bernadette has been missing and concerns she may have come to some harm, we made the decision to declare this a murder investigation yesterday morning.
'Whilst we hope we do find Bernadette alive and well, there is every possibility this may not be the case therefore my team and I will do everything possible to find out what has happened to her and bring any offenders to justice.'
Bernadette ran out of her car parents car on July 18, she contacted her family two days later, but was reported missing the following day.
