A man who murdered a fellow resident at his multiple-occupancy home has been jailed for life with a minimum of 20 years.
Gavin Casey, 31, was found guilty of the murder of Christopher Messenger at Birmingham Crown Court.
Casey attacked Messenger, 36, in February after becoming jealous when his ex-partner, who lived in the house, offered to make Mr Messenger a cup of tea.
He demanded that she made him one instead, before throwing a TV at her and going into Mr Messenger’s room, where he beat him.
His ex-partner followed him into Messenger’s room to check he was alright, at which point Casey turned on her too, punching her in the face.
She turned to run for help, and witnessed Casey stamping on Mr Messenger’s face before dropping a TV on him.

After the attack, Casey left the building to buy drugs, and was caught on video dancing and shouting “I’ve killed him!” in the car park.
He then climbed a gas tower and had to be talked down by officers, who arrested him.
In the video, he can be seen telling officers: “I’m gonna plead guilty anyway, they’re gonna give me ten years on Monday.
“And when I come out after doing my ten years… I’m gonna kill the geezer anyway” (watch the video above).
Mr Messenger had not died by this point - he was found severely injured by another housemate, and died three days later from his injuries.
Casey was sentenced to life in prison for murder, serving a minimum of 20 years.
He was also found guilty of assaulting his ex-partner.
'Showed no remorse'
Detective Inspector Paul Joyce, from Force CID, said: "This is a tragic case where a violent man flew into a jealous rage attacking and killing an innocent man.
"Mr Messenger was recovering from injuries he had sustained in a recent collision and Casey, knowing that Mr Messenger was at his most vulnerable, brutally attacked him.
"Casey did not give a second thought to what he did, instead he laughed about the despicable act he had just committed and left Mr Messenger dying in his room.
"I hope that today’s sentence will be of some comfort to Mr Messenger’s family and friends."
In a statement, Mr Messenger’s family said: “"It has been extremely difficult to sit and listen to the full details of our Chris’s death, a son, brother, uncle, nephew who was taken too soon in a brutal unprovoked attack. Sitting watching a man show no remorse whatsoever for his actions.
"Nothing will bring Chris back but we are glad that justice has been done.
"We are very thankful to the police for their hard work and support and all involved in getting justice for Chris. The witnesses who were brave enough to take the stand to help ensure that Gavin Casey was found guilty."
