Escaped Killer Returned To Mental Health Unit A convicted murderer who sparked a manhunt when he went missing from a mental health hospital has been found. Police had urged people not to approach Daniel Rosenthal, 58, who has paranoid schizophrenia and was described as "potentially dangerous." Officers launched a search after he was last seen at about 2.30pm on Saturday, when he went on a "routine, unsupervised walk" around the gardens of the low-security Southfield unit at Tatchbury Mount in Totton, on the edge of the New Forest in Hampshire. He was found in Southampton on Sunday and returned to the hospital. The Southern Daily Echo reported that in 1981, Rosenthal murdered his mother at their home in Hedge End after he had killed his father in France and that he chopped their bodies into pieces with a hacksaw. The Southfield unit treats people with "serious mental illness" and many of its patients have a criminal past. It is run by Southern Health NHS Foundation Trust, based at Tatchbury Mount. Dr Julian Lewis, Tory MP for New Forest East, questioned why Rosenthal was given the freedom of taking unsupervised walks. He said: "Whilst it is a relief that this man has been found, it is disturbing that someone regarded as a danger to the public - who should not be approached - was allowed to go for unsupervised walks."
