The history of events which led to the stabbing of Rachael Slack and her 23-month-old son Auden.
A report has found the murders of a pregnant woman and her young son by her ex-partner could not have been "reasonably predicted'.
Derbyshire Police has ridiculed a rumour that calling 999 could boost your battery charge.
Senior officers at Warwickshire Police have welcomed the launch of Clare's Law in the county.
Det Supt Steve Cullen said tackling domestic violence was a priority for the force.
'Clare's Law' will allow victims to apply to us to understand what their partners past history may be, and where it is appropriate to do so we will disclose information in order that victims may make an informed decision around their own safety.
Any disclosure will be part of a range of support measures Warwickshire Police and West Mercia Police will put in place to support victims.
We welcome the strengthening of the legislation to help us protect the most vulnerable from harm.
Anyone who would like a disclosure can visit their nearest police station, call 101 or go online to get more details.
Police and Crime Commissioner Ron Ball added:
Domestic abuse is a particularly pernicious form of bullying, it can take many forms and is never acceptable.
As a society, we can never condone the use of physical, or psychological techniques by one individual to control another.
I wholeheartedly welcome the adoption of Clare's Law and hope that the new powers will give people more confidence to seek help if they have concerns about domestic abuse.
Police in Warwickshire will soon have the power to tell people if their partner has a record of violence in the past, as part of an overhaul of the law to tackle domestic abuse.
The Domestic Violence Disclosure Scheme, also known as Clare's Law, will go live in the county on March 10.
It comes after Clare's Law launched in Derbyshire yesterday.
It gives people the right to ask police whether a new or existing partner has a criminal record. If it is revealed that the person in question may pose a risk, the police can then decide whether to disclose that information.
The scheme is named after Clare Wood, who was murdered by her ex-boyfriend George Appleton in Salford in 2009.
Clare’s Law is being launched across Derbyshire today. It forms part of a national focus on domestic abuse from 4-8 March. The scheme is named after Clare Wood, who was murdered by her ex-boyfriend George Appleton in Salford in 2009.
The scheme works in two ways:
A right to ask: This is where information is disclosed following a request from a member of the public.
A right to know: This is where police make a decision to disclose details when they receive information to suggest a person could be at risk.
Detective Superintendent Andy Stokes, Head of Public Protection at Derbyshire Police said:
“This is a national scheme that we hope will provide people with the information they need to make informed decisions about their relationships and to take relevant action.
“It is crucial that police and other agencies are made aware and can provide early intervention to help the victims."
Leon Lockhart has been sentenced to 13 years imprisonment after being found guilty of the manslaughter of Daniel Baker. More to follow...
A man has been found guilty of the manslaughter of a father from Derby - found collapsed on a street in South Normanton in July last year.
Leon Lockhart was found guilty of stabbing Daniel Baker after an eight day trial. Michaela Griffiths pleaded guilty to perverting the course of justice last November.
The jury were shown CCTV of the three on buses around the area following a chance meeting just hours before his death.
Mr Baker's family described him as a loveable rogue who left behind countless true friends. The pair will be sentenced tomorrow.
Derbyshire Police have charged a 23-year-old man with attempted murder, after a serious assault in Buxton on Friday.
Jake Grimshaw, from South Mews, Buxton, will remain in custody before appearing in court on Monday.
The attack took place at around 4.40pm, when officers were called to a disturbance on Fairfield Road.
A 36-year-old man was then taken to Wythenshawe Hospital in Manchester, where he remains in a serious but stable condition.
Christine Cassell, from the Derbyshire Safeguarding Children Board, says the deaths of Rachael Slack and her son, Auden, could not have been predicted or prevented, but that there are recommendations for areas of improvement where agencies work together to protect children.
The 38-year-old mother and her 23-month-old son were stabbed to death in Holbrook, Derbyshire, in 2010, by Rachael's ex-partner, Andrew Cairns, who then killed himself.
The bereaved partner of a Rachael Slack has told Daybreak he does believe more could have done to save her life, and said the police should have warned them her ex-partner had threatened to kill her.
Pregnant Rachael was stabbed to death along with her 23-month-old son Auden by her former partner Andrew Cairns in the picturesque village of Holbrook, Derbyshire, on June 2, 2010.
A serious case review said the murders could not have been "reasonably predicted", but Rachael's bereaved partner Robert Barlow disagrees.
He called on the police, mental health and social care services to communicate better with each other and warn women whose lives may be at threat from an ex-partner.
He added: "It would help me focus my...sheer disappointment, knowing that something is going to change the future, that Rachael and Audens are going to be better looked after."
