Oklahoma City – from www.dailymail.co.uk – A pregnant mother-of-four who has been missing since December 10 is believed to have been working as a Craigslist prostitute and police say she may have been murdered.

Oklahoma City Police say the length of time Jaymie Adams has been missing and the circumstances surrounding her disappearance has made them change the scope of the investigation.

Jaymie, 25, is believed to have been pregnant with her fifth child when she disappeared and police are looking into whether or not she was involved in prostitution.

Her husband Justin Adams was the last person to see her alive and was interrogated by police for five hours after her disappearance, but was released without charge.

His attorney Irven Box said they believe Jaymie was involved in online prostitution.

‘We think all of this may have to do with Craigslist … or someone she met there. We think there’s a strong possibility this may also be linked to prostitution,’ he told NewsOK.

Oklahoma City police Capt Dexter Nelson said: ‘Homicide will get involved, in cases like this, because of the length of time she’s been missing. There’s that, and the mysterious circumstances surrounding the disappearance.

‘Since she left her home no one has been able to locate her or call her on her cell phone.’

Mr Adams reported his wife missing in the early hours of December 10.

He told officers his wife said she was going to meet ‘a friend’ at McDonald’s around 11pm the night before.

The family van was found at the restaurant but she was not. Police seized the vehicle to look for evidence.

He said she sent a text message when she arrived at the restaurant, but that was the last he heard from her.

The couple have been married since February and have a four-month-old baby, police said.

In the days after she went missing, Mr Adams made an emotional TV appeal, urging the public to help bring his wife home safely.

He said: ‘She deserves to be at home with her family, our children need their mother.

‘My wife is a loving a strong woman. She’s an amazing mom, and amazing wife, we have three sons and she’s 2-month pregnant this week.

‘I’m begging that if anyone has any information about my wife or her whereabouts, call OKCPD.’

A Facebook page has been set up to try and find the missing mother.

Blake Parsons, the father of one of Jaymie’s children, told NewsOK he is not surprised she was involved in prostitution.

He described her as a loose cannon and said he would often wake up in the middle of the night to find her gone from the bed.

He said: ‘Some of us who knew her, when we heard this, we weren’t surprised. I don’t want anything bad to happen to Jaymie, and I hope they find her alive and healthy.

‘But we just think this was her past catching up with her.’
