Below is a transcript of the statement made by DCI Mark Oughton, senior investigating officer, following the conviction of Gary Allen for the murders of Alena Grlakova in Rotherham in 2018, and Samantha Class in Hull in 1997:
Today, my thoughts - and the thoughts of everyone at South Yorkshire Police - are with the families of Alena Grlakova and Samantha Class.
Both women were killed more than two decades apart by a very dangerous man.
Alena's death led to the largest investigation by SYP's Major Crime Unit in many years.
After our murder enquiry was launched, my team - and all those we worked with – were determined to secure justice for Alena's family and loved ones.
I am pleased with today's conviction and satisfied that Gary Allen faces a life sentence behind bars.
Although it will hopefully bring Alena's family some closure, we know it will never bring her back. Alena was a mother of four children. A daughter, a sister and friend. At the time of her death she was making plans to return to Slovakia to make a fresh start. Allen cruelly and violently took Alena's life from her, just as she was making plans for a brighter future.
I'd also like to take a moment to thank all the colleagues, partners especially CPS and the legal team who helped bring to court the best possible case against Allen. We worked particularly closely with the team at Humberside Police, who were just as determined as us to see Allen face the consequences of his despicable crimes, for Samantha and her family.
Finally, a thank you to Alena's family for all their support during this complex and wide-ranging investigation. They have conducted themselves with incredible dignity at this most difficult time.
