The mother of missing teenager Jayden Parkinson has posted a heartfelt plea over the disappearance.
Samantha Shrewsbury wrote a message on social media site Facebook saying: "My baby, my princess, my heart is so heavy, baby girl.
"I just want to see you walk through my door with a 'ta-dar'.
"I need you little lady, my heart feels so empty without you."
Police searching for missing teenager Jayden Parkinson have told ITV News that a number of factors surrounding her disappearance prompted them to launch a murder investigation.
Commander Superintendent Christian Bunt from Thames Valley Police said the fact that the teenager had "no access to finance" and had not used a telephone since she went missing on Tuesday had changed the nature of the investigation.
"She didn't have any additional clothes and she hasn't been on social media, which is highly unusual for a 17-year-old," he said.
The investigation into the disappearance teenager Jayden Parkinson is focusing on the village of Upton and a grassed area off Lydalls Road in Didcott, Commander Supt Christian Bunt told Sky News.
He said: "We have got two significant search areas at the moment. We continue to focus on the area in Upton just outside of Didcot and we understand that is having a big impact on the local community.
"We've got a lot of resources attached to the operation, over 100 officers, specialist search and investigative officers and it's also important to mention we have specialist officers with the family supporting them".
Thames Valley Police are continuing their search for missing 17-year-old Jayden Parkinson, with a police cordon in place near St Mary's church in Upton.
Det Ch Sup Andy Murray yesterday said Thames Valley Police's "main area of focus" was some farmland, with a search and rescue team with dogs carrying out an "extensive search" of the area.
Thames Valley Police have asked the public not to conduct their own searches for missing teenager Jayden Parkinson.
Commander Supt Christian Bunt said:
Police are continuing to search for missing teenager Jayden Parkinson who they believe may have been murdered.
Two men are in police custody on suspicion of murder in connection with the disappearance of the 17-year-old.
The teenager, from Oxford, was last seen in the Iffley Road area of Oxford mid-afternoon on December 3 and failed to return home that evening as planned.
A 17-year-old man was arrested after he attended a police station in Oxfordshire, while a 22-year-old was arrested at an address in Christchurch Road, Reading, on Thursday night.
Forensic officers have been examining the property.
Police investigating the disappearance of Jayden Parkinson have said they are planning to scour a rural area in Upton for "up to a week".
Detectives said they are looking for a man spotted in Upton carrying a large suitcase. Detective Chief Inspector Andy Murray told a news conference that the man was notably struggling to "manage" the heavy case.
Jayden's family are distraught, police said, as they announced their missing persons investigation into her disappearance had been changed to a murder inquiry.
Detective Chief Superintendent Andy Murray said the family still have hope.
"They've still got hope but they are distraught and they want their daughter to come home.
"I'm afraid the detective in me leads me to conclude that Jayden may well have been murdered and that's why we have approximately 50 detectives out there still trying to find Jayden, still trying to find evidence that might lead to somebody being convicted if she has been murdered."
Thames Valley Police have said a young man seen struggling with a suitcase could hold the key to her disappearance, and are eager to talk to him.
Detective Chief Superintendent Andy Murray said police were now focusing on trying to find a man who was seen with a large suitcase in a field in the small village of Upton in the early hours of December 9.
The man has been described as about 20, white, about 5'6" tall of medium to slim build, with short dark hair. The suitcase was described as light coloured, probably made of canvas material.
Police searching for missing teenager Jayden Parkinson in Oxfordshire have confirmed their missing person investigation is now a murder inquiry, despite no body having yet been found, and they are searching for a man seen with a suitcase.
