The Tragic Story of Beatrice Mwende: The Mathematics Teacher Whose Despair Ended in the Death of Her Four Children
The evening of June 26, 2020, began like any other night in the home of Beatrice Mwende, a 42-year-old mathematics teacher and mother of six living in Kabati Estate, Naivasha.
She had dinner with her children. They spent time together and watched television.
But beneath the ordinary family routine was a woman carrying struggles that, according to her family, she had largely kept to herself.
Within hours, four children would be dead.
Their mother would be arrested.
And a family would be left trying to understand how a woman who had cared for her children could commit such a devastating act.
The victims were Melody Warigia, 8; Willy Macharia, 6; Samantha Njeri, 4; and Whitney Nyambura, 2.
Two of Beatrice’s other children, Alex and Bravo, were not at home that night.
A life that slowly fell apart
Beatrice had studied for a Bachelor of Education degree at Laikipia University and had worked in a local non-governmental programme run through a Catholic Church.
But the COVID-19 pandemic disrupted lives and livelihoods across Kenya. Beatrice lost her job, and her financial situation deteriorated.
According to accounts presented in court, she struggled with rent and an outstanding Kenya Power bill reportedly running into more than KSh1,400.
The financial pressure was accompanied by emotional turmoil.
She was also dealing with the collapse of a relationship. In a letter she left behind, Beatrice wrote about a man she said she had loved deeply but who had chosen another woman.
“I loved him dearly but he loved another woman,” she wrote.
She also blamed her financial struggles for the desperate state of mind she had reached.
In another heartbreaking passage addressed to her older son, she wrote words that would later become part of the evidence surrounding the tragedy:
“If only I had a stable job, I would not have killed your siblings.”
The night everything changed
On the night of June 26, Beatrice was at home with the four children.
The family ate together. They watched television. To anyone observing from outside, it appeared to be an ordinary family evening.

But later that night, the unthinkable happened.
Beatrice strangled her four children.
After the killings, she went to sleep.
The following morning, she left the house and travelled to a lodging she had rented in Kayole.
It was there that she contacted members of her family and revealed what had happened. She asked them to pray for her.
She also left behind detailed instructions for her older son, including what should happen to her belongings and how he should care for his younger brother.
She wrote:
“As for the house rent. I have paid up to April. May and June are not yet paid… You can sell all the items if need be.”
She also asked her son to take care of Bravo, telling him to become his younger brother’s “Guardian Angel” and urging the siblings to learn to tolerate each other despite their differences.
She even gave instructions concerning the children’s burial and indicated that she had purchased new clothes for them.
Her letter included a passage from John 14:1:
“Do not let your hearts be troubled. You believe in God; believe also in me.”
She appeared to understand that she would face the consequences of what she had done.
“I know I belong to jail… in fact, I know I will spend the rest of my life behind bars but I am prepared for it,” she wrote.
Arrest and a family’s shock
Police arrested Beatrice on June 27, 2020, at the Kayole lodging.
She was reportedly composed when officers brought her to Naivasha Police Station.
For her family, however, the tragedy was almost impossible to comprehend.
Her brother, Jackson Kiambu, later said the family had not realised just how much she was struggling.
“She never shared with anyone what she was going through, including financial challenges. We were not aware she was battling stressful moments,” he said.
The four children were eventually buried together in Kinangop, their coffins placed side by side in a single grave.
The family was left mourning four innocent lives lost in a tragedy that had unfolded behind closed doors.
The courtroom battle
Beatrice was charged with four counts of murder.
She initially denied the charges but later changed her plea after consulting with her lawyer.
During the proceedings, she claimed that she had been under the influence of evil spirits or demonic forces at the time of the killings. She also linked the alleged possession to her former relationship.
The court, however, rejected the explanation.
Medical and psychiatric evidence presented before the High Court indicated that Beatrice was mentally sound when she committed the offences. The court therefore found her criminally responsible for the deaths.
In March 2023, High Court Judge Grace Nzioka sentenced Beatrice Mwende to life imprisonment on each of the four murder counts.
A tragedy that left painful questions
The case remains one of those tragedies that leaves more questions than answers.
How did a mother struggling with financial hardship and emotional pain reach a point where she believed there was no other way out?
Why did those closest to her not realise the depth of her suffering?
And could intervention have changed what happened that night?
Her brother’s account that Beatrice had not revealed the extent of her struggles highlights a painful reality: sometimes, people can be fighting overwhelming battles while appearing perfectly normal to everyone around them.
Financial hardship, unemployment, relationship breakdown and emotional distress can become unbearable when someone feels completely alone.
But despair does not make violence inevitable, and there is always a need to seek help before a crisis becomes irreversible.
For families and friends, sometimes the simplest question can be powerful:
“Are you really okay?”
And when someone says they are struggling, listening without judgement can be the first step toward getting them the help they need.
Four children — Melody, Willy, Samantha and Whitney — lost their lives in a tragedy that can never be undone.
May their innocent souls rest in peace.
