A coroner recommends changes in offender management after seven other people were injured.
A man was stabbed to death during a city centre rampage after systemic failures enabled his killer to roam the streets, a coroner ruled.
Jacob Billington, 23, was knifed by Zephaniah McLeod, who also injured another seven people in Birmingham.
Following an inquest into his death, coroner Louise Hunt said she would recommend offender management changes.
McLeod, who has paranoid schizophrenia, was jailed for life for manslaughter in 2021.
Ms Hunt said agencies had failed to communicate effectively and had not prepared properly for the release from prison of Jacob’s killer.
Jo Billington, Jacob’s mother, also said there had been systemic failings and that it looked like no lessons had been learned between her son’s death and the Nottingham stabbings in which three people were killed last summer by another man who has paranoid schizophrenia.
Anne Callaghan, the mother of Jacob’s best friend Michael, who was seriously injured in the attacks, said: “It is depressing seeing the lack of communication and information sharing.
“The lack of public protection is frightening.”
The two-week inquest heard McLeod had been released from prison in April 2020 and had numerous previous convictions including for assault, for possessing a firearm and bladed weapons, and drugs offences.
