A ‘callous’ man who brutally murdered his girlfriend, stabbing her 39 times, has been handed a life sentence.

Owen Pellow, aged 43, will spend a minimum of 17 years behind bars after killing 36-year-old Lisa-Marie Thornton at their Berrow Road home in Burnham-On-Sea last November.

Pellow was convicted and sentenced at Bristol Crown Court yesterday (Tuesday).

He claimed Ms Thornton stabbed herself, but a jury took less than three hours to find him guilty of murder.

The court saw footage of Pellow being arrested by Avon and Somerset Constabulary officers on November 23, which has been released to the Mercury.

Pellow appeared dazed and confused as officers removed him from the couple’s home before claiming ‘she’s done herself in, she’s tried killing herself’ and ‘she’s my love’.

He later pleaded with officers not to arrest him, saying ‘I was supposed to be going to get some baccy’.

Ms Thornton leaves behind three daughters, who spoke after Pellow was jailed.

One said: “I won’t have my mum to help prepare me for prom, she won’t be able to see me at my wedding and her grandchildren won’t ever know who she was.

“I can’t understand how someone could be so callous to take such innocent life wrongly away from them and their family.”

Ms Thornton’s mother told of her ‘broken heart’, adding: “I’m crying most days and just can’t believe she’s gone.”
