A pub chef who beat his girlfriend to death because he was paranoid she was cheating on him has been jailed for life.
Jordan Matthews will serve a minimum of 18 years in prison for the "relentless and remorseless" attack on student Xixi Bi.
Matthews hit Bi dozens of times after seeing what he wrongly believed was a message from dating app Tinder on her phone.
Bi suffered 41 injuries including bruising and multiple fractures, including a broken jaw and ribs.
The prolonged assault started at 1.30am on August 19 last year at their flat in Llandaff, Cardiff. At 8.30am she collapsed due to complications from her injuries and Matthews called the emergency services.
Matthews originally told police he was a black belt in karate but later admitted that was not true. He pleaded guilty to manslaughter but denied murder.
The jury rejected the claim that he had not intended to hurt Bi and found him guilty of murder after a 10-day trial.
He was sentenced today (February 21) at Cardiff Crown Court, Justice Nicola Davies said the assault was the "tragic culmination" of a course of physical and verbal abuse over a number of months.
