Meet Brother Roland McKoy 53, of Oswald's Mead, Hackney, east London ...
... on 17 December 2014, a judge imprisoned him for a minimum 35 years after a jury at the Old Bailey him guilty of double murder.
Valerie Forde, 45, and her 23 month-old daughter Real-Jahzarah McKoy were found dead at their home on 31 March 2014.
Police broke down the door of the three-storey house in Oswald's Mead, Homerton, east London, after receiving a 999 call from relatives at 9.11 a.m.
Ms Forde, an office manager for the Hackney Marsh Partnership, and her daughter were pronounced dead at the scene.
Post-mortem examinations later revealed Valerie Forde had died of multiple injuries and her daughter had died of incised wounds to the neck. Valerie had suffered up to 17 blows from a hammer, a series of cuts to her face and neck and eight stab wounds to her stomach.
Valerie's 53 year-old partner was found injured at the address was arrested on suspicion of murder and taken to hospital for treatment. He was discharged from hospital on 9 April and taken into custody.
On 10 April detectives charged Roland McKoy with two counts of murder.
McKoy, who emigrated from Jamaica in the 1980s, went on trial at the Old Bailey on 8 December 2014. The prosecution claimed McKoy murdered his partner and daughter out of 'anger and resentment' after being told to move out of the family home.
Jurors heard how the couple began a relationship in 1995 but it began to deteriorate in 1999 when Ms Forde discovered McKoy was married and was still seeing his wife and two children. Although the relationship improved after the birth of Real-Jahzarah, there were often rows about McKoy's failure to contribute to the household.
In December 2013 Valerie Forde gave McKoy a deadline of 31 March 2014 to leave unless he paid £150 a month towards rent, food and the upkeep of the children.
Ms Forde also reported McKoy to police on 12 February 2014 after he allegedly told a neighbour he was going to kill her and her family by burning down the house.
The start of the attack was overheard by Ms Forde's eldest daughter Carrise over the phone after she received a call at 9.06 a.m. on 31 March.

Police officers arrived at 9.17 a.m. to find no sign of a disturbance. They forced entry and found both Valerie and Jahzarah dead. McKoy had cuts to his neck and stomach and vomited bleach after being roused by paramedics.
A note was found covering Valerie Forde's face reading: '
"Valerie Forde you never stop playing derty ticks (sic) for many years on all people places and things you targets. Now the world must see the sudden destru..tions you creates in our families, our home and on yourself. Our fame in history. Roland."
Prosecutor Ed Brown QC said: 'A true and full understanding of the reason for these terrible killings may be beyond sensible comprehension but all of the available evidence points to little more than anger and resentment as the cause.'
McKoy, who had previous convictions for drugs and benefit offences, claimed he acted in self defence after Ms Forde killed their daughter.
On 17 December McKoy was convicted of both counts of murder and jailed for life with a minimum of 35 years before parole.
The family of Valerie Forde said in a statement: "No matter how many years he receives it will not bring Valerie and Jahzara back. The pain will still continue for our family for the rest of our lives. His actions have destroyed the lives of Valerie and Jahzara's family, friends and the wider community in Hackney. Their deaths will not be in vain."
Investigating officer Detective Chief Inspector Charles King, of the Homicide and Major Crime Command, said: "Research has shown that women are at greatest risk of homicide at the point of separation or after leaving a violent partner.
What Roland McKoy did on that day in March almost defies belief, but it is a stark warning that extreme violence within such relationships is a very real possibility.
"McKoy lost control as the reality hit home that Valerie was adamant he must leave and carried out a horrific attack with a variety of weapons. Not only did he vent his fury at his partner but he also killed his baby daughter."
Following the murders, the Metropolitan Police's Directorate of Professional Standards referred the case to the Independent Police Complaints Commission, due to the victim's previous contact with police regarding alleged domestic violence, which is investigating and their probe is understood to be near completion.
Five police officers are being investigated for alleged gross misconduct and four for misconduct. A police staff member has also been served notice of investigation.
Prosecutor Ed Brown QC said: "It is plain that the defendant had attacked Valerie Forde with the hammer, slashed her face and neck with the machete and stabbed her multiple times with the screwdriver.
"It is equally clear from the evidence that the defendant used that same machete to cut Jahzara's neck from one side to the other. Each attack was a brutal one."
Judge Charles Wide QC told McKoy: 'You have been convicted of the deliberate, horrific killing of Valerie and your 22-month-old child Jahzarah.
'You did it out of spite and resentment that Valerie at long last had the strength and resolution to say that enough was enough and you had to go.
'She had given you three months and you had done precious little. You thought she was going to back down but she didn't and that was an affront to your monstrous egotism.
'There was real deliberation here, you went downstairs to get the weapons and this is real substantial aggravation.
'Three of them - a hammer, a screwdriver, a fearsome stabbing weapon, and a machete - and you took them upstairs where your attack on Valerie, who was simply getting ready to go to work, was savage and sustained.
'One weapon after the other you used, you put one down and picked up the other one.
'It involved repeated, heavy blows with the hammer to the head, heavy blows with the machete to the head, and we have seen the dreadful injuries you caused, and repeated stabbing with the screwdriver to the body.
'On and on this brutal attack continued not less than 33 blows and when you had killed her you then turned your attention to a 22-month-old child.
'We have heard the description of what you did to her, plainly with the machete at the throat.
'Your lethal actions have left children without a mother and without their sister and caused grievous loss and distress to a close, loving family and community.
'If you survive you will be an old man before you became eligible to be considered for release.
'What struck me and everybody during the trial is that you showed not an atom of regret at what you did. Having slain Valerie, your partner for years and years, and your 22-month-old daughter, on whom we are told you doted, no regret at all.'
