1830, is an example of this:

"LONDON ADJOURNED SESSIONS.

"TUESDAY.--BODY-SNATCHING.--A well-known pilferer of graves, named Clarke,
was tried upon an indictment, charging him with having stolen the body of
a dead child, aged about four years, which had been under the care of a
nurse named Mary Hopkins. The facts which came out in evidence are as
follows: The deceased was the daughter of a woman of the town, residing in
Shire Lane, and had been kept at the nurse's lodging, which was in the
same neighbourhood. She died on a Friday, and Clarke, whose ears were
described as 'quick to the toll of the passing bell,' paid the nurse a
visit the next morning, under pretence of hiring a cellar under the house.
He took occasion to notice the poor woman's son; said it was a pity to see
the boy idle, and that he should have immediate employment, and called
again with evidences of still stronger interest in favour of the family.
'By the way,' said he, 'I understand you have had a death lately.' 'Yes,
sir,' said the nurse, 'a poor little girl is departed.' 'Poor little
dear,' cried the snatcher, 'I should like to look at the little innocent.'
He was forthwith led into the front parlour, where the body lay in a
coffin, and observing that its position was favourable to his intention,
he sympathized with the nurse, and said, 'We must all come to this sooner
or later,' and then he went to get a half-pint of summut to comfort them.
The nurse disposed of a glass, which presently set her in a profound
sleep, and when she awoke the body of the babe was gone. It appeared that
the snatcher, after having quitted the house, as if for good, returned,
and opening the parlour-window hooked out with a stick the corpse of the
child, and went off with it towards a market that is open at all hours,
near Bridgewater Square. However, a police officer, who knew his trade,
laid hands upon him, telling him he was wanted. The snatcher then threw
down the child and took to his heels, but was apprehended and lodged in
the Compter. The nurse proved the identity of the body. Upon her
cross-examination, by Mr. Payne, she stated that the mother had not been
to see the deceased for four or five days before the death. The Jury
returned a verdict of Guilty, but some of them audibly spoke of
recommending the prisoner to mercy, but made no appendage to that effect.
The Recorder sentenced the prisoner to be imprisoned for the space of six
calendar months."
