After a private meeting with Nowak’s father Mark Nowak, mother Lucy Ross and stepmother Katie Woodcock, Sir Keir said he was moved to learn about Henry’s “kindness, his warmth, and his love of football” and his bright future ahead which was “cruelly stolen from him in appalling circumstances”.
“Henry deserves a legacy that goes beyond this awful tragedy, and I am committed to making that happen,” Sir Keir said.
“I am determined that we do everything in our power to prevent other families from suffering such a devastating loss.”
The Independent Office for Police Conduct (IOPC) is looking into Hampshire Constabulary’s actions on the night of Nowak’s murder.
The prime minister said: “We will be unflinching in taking whatever action is required to right the wrongs in this case.
“It is our duty now to ensure that lessons are learned, that justice is delivered and that we choose unity and progress over division and hatred. This is the only way to honour Henry’s memory.”
An inquest jury into the teenager’s death will look at whether any “act or omission by a police officer” caused or contributed to his death. It is due to take place in September next year although the coroner said on Thursday he hoped the date could be brought forward.
