A former army man convicted of murdering his wife and their two children has been sentenced to life imprisonment, closing one of Kenya's most disturbing family murder cases — one that shocked the country and remained unresolved for years.
Ex-Kenya Defence Forces (KDF) major Peter Mugure was sentenced on Tuesday after the High Court ruled that he had carefully planned the killings in 2019, before burying the bodies in a shallow grave in Laikipia County.
"I have gone through the victim impact assessment report and taken into consideration that the murders of the three were barbaric," the judge said.
The sentence came days after the court found Mugure guilty of murdering his wife, Joyce Syombua Maua, 31, their 10-year-old daughter Shanice Mugure Mwaura, and five-year-old son Peter Mwaura Junior, also known as Prince Michael.

State prosecutors had asked the court to impose the death sentence, saying Mugure had wiped out his own family in a carefully executed plan. The judge instead handed him life imprisonment after considering the impact of the killings on the victims' family, the circumstances of the case, and the time he had already spent in custody.
Mugure: I disagree with sentence
Moments after he was sentenced, Mugure told the court he disagreed with both the conviction and the punishment.
"With tremendous respect to the court, I am unable to agree with the verdict," he said.
The murders happened in October 2019, after Mugure invited Joyce and the children to visit him at the Kenya Air Force base in Nanyuki. The family travelled from Nairobi expecting to spend time together. They never returned home.
Evidence presented during the trial showed they spent the night at Mugure's house before leaving the military base for lunch at Kilimara Springs Hotel. That was the last time they were seen alive.
The court found that after returning to the military base, Mugure killed all three. He then packed the bodies into body bags, loaded them into the boot of his car, and drove them to Thigithu, where they were buried in a shallow grave.
"Evidence shows that the accused murdered his wife and two children, stacked their bodies in body bags and hid them in the boot of his car before burying them at Thigithu," Justice Muya ruled.
Returned to scene of crime
The judge said evidence showed Mugure had visited the burial site three days earlier with another military officer, and that the trip showed he had already chosen where to dispose of the bodies before carrying out the killings.
"This goes to show that the accused had hatched the plot... even before killing them," the judge said.
Pamba told the court he found Joyce's body inside a transparent body bag, while the two children had been placed in a bathtub. The bodies were tied with ropes before being squeezed into Mugure's car. The two men later buried them before covering the grave with soil.
Pamba later entered into a plea bargain with prosecutors, pleading guilty to a lesser offence and receiving a five-year prison sentence. His evidence was backed by DNA tests, mobile phone records and forensic findings.

Government Chemist analysis confirmed the remains recovered from the grave belonged to Joyce and the two children, while DNA also confirmed Mugure was the biological father of the children. An autopsy by Chief Government Pathologist Dr Johansen Oduor found Joyce died from severe head injuries, while both children had been strangled.
Possible motive: Child support

The prosecution also pointed to a possible financial motive. Before the murders, Joyce had obtained court orders requiring Mugure to pay Sh25,000 every month for child maintenance. Prosecutors said he made only one payment before inviting the family to Nanyuki.
The judge dismissed Mugure's claim that he later handed the children to one of Joyce's friends — no such person was identified or called to testify. Instead, the court found overwhelming evidence that Joyce and the children never left the military base alive.
Justice Muya concluded that the prosecution had proved its case beyond reasonable doubt, finding that the murders were deliberate, carefully planned, and followed by an elaborate attempt to cover up the crime.
