A second report on the death of Cleveland kidnapper Ariel Castro has found that he did commit suicide in his prison cell.
A state prisons report last month suggested Castro may have accidentally hanged himself while attempting to achieve a sexual thrill.
However the latest report says all available evidence, including a shrine-like display in Castro's cell and an increasing tone of frustration in his prison journal, point to suicide.
53-year-old Castro had just begun serving a life sentence plus 1,000 years for imprisoning and raping three women in his shuttered house for a decade.
Castro was found hanging in his cell in September.
Michelle Knight was tied by her arms, neck and feet and "hung like an ornament", she told US TV show Dr Phil.
Watch her describe her ordeal:
Michelle Knight, who spent 11 years in captivity after being kidnapped by Ariel Castro, has relived horrifying aspects of her ordeal in a US TV interview.
The 32-year-old told the Dr Phil show how Castro "tied me up like a fish, an ornament on the wall."
Castro, who was jailed for life, died in an apparent suicide in prison in September.
Cleveland kidnapper Ariel Castro, who was found hanging in his prison cell in September, may not have committed suicide but could have died accidentally, according to a report from the Ohio Department of Rehabilitation and Correction.
The report said prison officials had falsified logs and failed to make regular checks on Castro's cell on 3 September, the day of his death.
The possibility of accidental death was disputed by Franklin County coroner Jan . Gorniak, who called his death "a hanging suicide" in an interview with the Cleveland Plain Dealer newspaper.
Castro was serving a sentence of life plus 1,000 years for the abduction, torture and detention of three young Cleveland women. He was taken off suicide watch in June, but should have been monitored by guards every 30 minutes.
On the day of Cleveland kidnapper Ariel Castro's death in his prison cell, prison officers falsified logs and didn't properly complete rounds, according to a state report released today.
A review by the Ohio Department of Rehabilitation and Correction found that rounds were missed and logs falsified in the six hours before Castro, 53, was found hanging in his cell on 3 September.
Castro had been serving a sentence of life plus 1,000 years for the abduction, torture and detention of three Cleveland women. He had been taken off suicide watch in June but was supposed to have been checked on every 30 minutes by guards.
The lawyer for the Ohio kidnapper Ariel Castro, who held three women captive for almost a decade, has said that his client should have been tested to see whether suicide watch was needed.
Craig Weintraub told Cleveland newspaper the Plain Dealer that he did not understand the rationale behind denying Castro the opportunity to be assessed for suicidal tendencies.
Being on suicide watch would have meant that he was checked up on every 15 minutes.
Mr Weintraub added: "He's still a human being, this is still a civilised society. There's still an obligation to prevent our inmates from committing suicide."
The victims of Ariel Castro - Michelle Knight, Gina DeJesus and Amanda Berry - have been made aware of his suicide, but will not be commenting, according to a CNN editor.
A review is underway after Ariel Castro was found hanged in his Ohio prison cell late on Tuesday, officials said.
Castro had been incarcerated since August 5 at the Correctional Reception Center, a prison processing facility outside Columbus, the state capital, about 150 miles southeast of Cleveland.
Prison medical staff tried to revive Ariel Castro after he was found hanging in his prison cell but failed, according to CNN.
Castro was taken to The Ohio State University Wexner Medical Center where he was pronounced dead at 10.52pm local time.
Castro's brother-in-law, Juan Alicea, told CNN that the family was notified by a warden at about 1 am.
Ariel Castro was being held in protective custody in isolation from other inmates at the Correctional Reception Center in Orient, Ohio when he was found dead last night.
According to media reports in the US, he was being checked on every 30 minutes.
