Gary Allen case

Gary Arthur Allen (born 27 September 1973) is a British convicted murderer serving life imprisonment for the murders of Samantha Class and Alena Grlakova, two sex workers who he killed 21 years apart, in 1997 and 2018. Allen first stood trial for Class's murder in February 2000, but was acquitted by a jury at Sheffield Crown Court. He then went on to assault two sex workers in Plymouth within days of his acquittal, and would later confess to murdering Class during an undercover police operation staged in 2010. It was not until a change in the law regarding the rules of double jeopardy in England and Wales, whereby a defendant could not stand trial twice for the same crime, together with other cases involving the double jeopardy rule, and after he committed the second murder in 2018 that Allen was brought to justice. Following a seven week trial in 2021, also held at Sheffield Crown Court, he was convicted of both murders, and sentenced to life imprisonment with a minimum term of 37 years. He will become eligible for parole in June 2057.
