A man has admitted fatally stabbing his own brother at least 36 times while he was on bail for arson.
Taylor Mitten, 23, killed brother Jack, 25, in September last year, before going on the run from police.
Mitten knifed his brother in the head, chest, and neck before shaving his beard to disguise himself.
A manhunt was launched and he was arrested three days later.
Mitten was already on bail from the Crown Court for conspiracy to commit arson and other offences when he carried out the killing.
The brothers' aunt found Jack’s body at his home in Lindum Road, Worthing, on September 3, 2025.
Emergency services were called to reports of a man suffering serious injuries.
Despite paramedics battling to save him, the 25-year-old was pronounced dead at the scene.
Detectives named Mitten as the man they wanted to speak to in connection with the killing and warned the public not to approach him.
He was subsequently arrested in Curzon Close, Worthing, on suspicion of murder on September 5.
Prosecutors previously told Crawley Magistrates Court that Mitten left work on the day of the killing and went to the address where his brother was staying.
Mitten appeared by video link at Lewes Crown Court on May 21 where he pleaded not guilty to murder.
At Lewes Crown Court in Hove today (September 11) he pleaded guilty to manslaughter by diminished responsibility.
When he was asked if he had killed his brother, he replied: “Guilty”.
After he was arrested Mitten assaulted a female police officer.
He had already pleaded guilty to setting fire to a Nissan Qashqai on June 2, 2020.
He will be sentenced next month.
Members of the Mitten family have been supported by specialist officers from Sussex Police.
