Body Found In Poole Confirmed As Samantha Henderson's
A body, discovered in a lake in Poole, has been formally identified as murdered mum-of-four Samantha Henderson.
Dorset Police confirmed that the body found at Ham Common on Friday was the 25-year-old's.
Her boyfriend Dominic Isom, 27, of Corfe Castle, pleaded not guilty to her murder when he appeared at Winchester Crown Court on Friday. Isom has been remanded in custody to stand trial on 13 July.
Police had already said yesterday that they were ``confident'' the body was that of 25-year-old Ms Henderson.
She has not been seen since leaving Corfe Castle Primary School in Dorset on 21 January at 3pm.
Ms Henderson, who has children aged six, four, two and one, was reported missing on 22 January at 8.43am.
A post-mortem examination on Ms Henderson's body showed she was violently attacked around the head and neck.
Detective Inspector Neil Devoto, who is leading inquiries for Dorset Police's major crime investigation team, said:
''Although we have recovered a body and a man is charged with murder, it is still vital that people come forward with any information that could help us build a picture of exactly what happened.
''Samantha's death has understandably shocked local people, who have rallied around her family, friends and neighbours in both Corfe Castle and her original home town of Poole. Her close family are being supported and regularly updated by specially trained family liaison officers.
``They have asked for privacy at this sad time.
''I would like to thank the public for their ongoing support to officers carrying out this investigation and their patience while we conduct searches.
``Their continued caution on social media is also appreciated and important, as inappropriate comments could cause further hurt to her family or potentially prejudice future criminal proceedings.''
Police want to hear from anyone who saw her blue Peugeot 307 estate car with the registration number HV04 ZFM being driven around the Corfe Castle or Ham Common areas from 3pm on 21 January.
A spokesman said:
``Detectives reiterated their thanks to the public for their patience during the searches and asked that people continue to respond to the appeal for sightings of her car.''
Witnesses and anyone with information should call Dorset Police in confidence on 101, quoting Operation Cavalier. Alternatively, call the free and anonymous Crimestoppers line on 0800 555 111 where mobile phone tariffs may apply.
