 Daniel Rosenthal, Convicted murderer missing from mental hospital
Daniel Rosenthal went missing from Tatchbury Mount Hospital in Totton
The public have been warned not to approach convicted murderer Daniel Rosenthal, 58, who went missing during an unsupervised walk around the grounds of Tatchbury Mount Hospital in Totton at 2.30pm on Saturday.
Police say are currently carrying out an “extensive” search for the killer. A spokesperson said: “Daniel has been known to visit various areas of the New Forest and Southampton.
“Police are urging members of the public to report any sightings of him by calling 999 and should not approach him, as he is potentially dangerous.”
Rosenthal, who wears glasses and walks with a hunch, was nicknamed the “mad scientist” when he was jailed for life in 1981 after dismembering his mother's body with a hacksaw.
The hospital where he is a patient, run by Southern Health NHS Foundation Trust, is just 15 miles from his former family home in Hedge End, near Southampton.
“Police are carrying out an extensive search for a patient from Tatchbury Mount Hospital, Totton, who has been missing since around 2.30pm yesterday,” a spokesperson said. “Daniel Rosenthal, who is 58-years-old, is diagnosed with paranoid schizophrenia and is a convicted murderer.”
“He was last seen at about 2.30pm, when he went for a routine, unsupervised walk around the gardens of the hospital.”
He is described as 5ft 2ins tall with short, greying, brown hair cut in a “basin style fringe” and he walks “with a hunch and a shuffle”.
He was wearing glasses with a metal rim and last seen wearing 'closed in' sandals, light brown, baggy, cord trousers and a long-sleeved cream-coloured shirt with buttons down the front.
Rosenthal was jailed after Winchester Crown Court heard hacked his father Milton to death in Paris, then hid the body in a British bin bag in a forest 100 miles from the French capital.
He then returned to England and killed his 60 year old mother, Leah Rosenthal, cutting up her body with a hacksaw at their house.
Her body was never found and police believe her remains were unwittingly carted off by dustmen. He could not be charged with the murder of his father.
Rosenthal was dubbed “the mad scientist” because of experiments he carried out on chicken eggs and embryos in a 'lab' he built in the living room.
He claimed to be a 'genius' and would leave bloodied feathers and chicken remains - the remnants of his bizarre experiments - in bags for the dustmen.
The home in Hedge End was finally sold for £50,000 in 1994 and Rosenthal collected a sum of £16,000 despite serving a life sentence.
At the time a spokesman for the solicitors' firm dealing with his mother's will said they hoped he would never be able to spend the money.
She added at the time: "Our worst nightmare is of Daniel Rosenthal on the streets again.
