Gosport MP Caroline Dinenage says she hopes lessons will be learned from the death in prison on the same day of two men accused of stabbing attacks.
They included a Gosport man accused of attacking a 22-year-old with a knife.
No-one is going to get punished now for stabbing my son.Victim’s mum
Daryl Hargrave, from Agnew Family Centre, in Gosport, was arrested after getting into a fight with a fellow resident.
But after being remanded in custody on July 13, Hargrave’s body was discovered in his cell at HMP Winchester.
His death came just hours after Richard Walsh, who had been accused of stabbing two boys, aged 12 and 13, in Havant, was found hanged in his cell at HMP Belmarsh.
The mother of the victim Hargrave was accused of stabbing said she was shocked by the news.
‘It was shocking when we found out, we didn’t know what to think,’ she said.
‘No-one is going to get punished now for stabbing my son. He is still suffering from what happened and Hargrave’s death has made him worse.
‘He just keeps going over things in his head.’
She added: ‘It is difficult to know what to think.
‘Obviously he needed some help and he didn’t seem to get it while in custody.
‘But it has ended now and we can start to get closure.
‘I feel sorry for his family, too. We don’t know what he went through and what help he obviously needed.’
Hargrave had appeared at Portsmouth Magistrates Court charged with grievous bodily harm. His defence lawyer did not ask for bail and he was remanded in custody.
A Prison Service spokesman confirmed that he was found unresponsive in his cell on July 19.
Staff attempted CPR and he was taken to the Royal Hampshire County Hospital in Winchester but was pronounced dead at 4pm.
Walsh, of no fixed abode, was also found unresponsive in his cell on the same day at Belmarsh prison at around 11am.
Ms Dinenage, who is also parliamentary under secretary of state at the Ministry of Justice, said both the deaths were a tragedy.
‘The dedicated custody staff work hard every single day to provide support to vulnerable and often aggressive offenders,’ she said.
‘However every self-inflicted death is a tragedy.
‘We must work hard to learn from any incident and share good practice.’
Ms Dinenage added there would be an investigation into both deaths by the independent Prisons and Probation Ombudsman.
