Wanjala aloitti murhaamisen ollessaan vasta 16-vuotias - saman ikäinen kuin osa hänen uhreistaan. Nairobin laitamilta heinäkuussa löytyneet neljä uhria oli kuristettu, ja heitä oli hakattu päähän tylpällä esineellä. Wanjala esitti jalkapallovalmentajaa ja sai tällä verukkeella uhrinsa tulemaan kanssaan pois muiden ihmisten näkyviltä.
Keniassa on noussut ääniä vaatimaan maan poliisijohtajan eroa. Sarjamurhaajan lynkkaus on yksi merkki siitä, että poliisiin ei luoteta.
"Olisin tahtonut kysyä häneltä, miksi hän teki tämän - tappoi lapsemme julmasti ja jätti meidät kärsimään tuskissamme", sanoi Grace Adhiambo, 16-vuotiaan Brian Omondin äiti. Brian oli yksi heinäkuussa löydetyistä neljästä surmatusta.

By Emmanuel Igunza
BBC News, Nairobi
A mob in western Kenya has killed a self-confessed serial killer who escaped from custody two days ago, police say.
Masten Wanjala, 20, was traced by villagers to a house in Bungoma town and beaten to death, they say.
Authorities had launched a massive manhunt for the fugitive who admitted to killing more than 10 young boys during a five-year period.
He also confessed to drugging them and in some cases drinking their blood.

"I would have loved to see him in court, so that I get to know why he did this - why he brutally killed our children and left us with pain," Grace Adhiambo said.
The badly decomposed body of her teenage son Brian Omondi was one of four recovered by police on the outskirts of the capital Nairobi in July.
A post-mortem carried out by the government pathologist showed they had been strangled and hit on the head with a blunt object.

Wanjala killed his first victim when he was just 16 years old, a similar age to some of his victims.
He posed as a football coach to lure his victims to secluded areas, after which he attacked them.
In some cases he took them as hostages for ransom.
The killings took place in Nairobi, and areas of eastern and western Kenya.
Three police officers who were on duty when he escaped on Wednesday have been charged with aiding the escape of a suspect and negligence.

Wanjala's killing by mob justice two days later however is a tragic reminder of the deep anger, hate and frustrations that many Kenyans feel for the National Police Service.
Kenyans saw this as an open-and-shut case, which the police bungled.
After more than three months of investigations, Kenyans are asking why was Wanjala never taken to court to face murder charges?
It raises questions about Kenya's judicial process - whose wheels often grind slow, and in this case, were completely broken, destroying the hopes for justice for families of the victims.
