In 2012, we became unwilling witnesses to a series of murders and rapes, in the misty villages of Kotakethana and Kahawatte, in the district of Ratnapura. The victims were all women, and the perpetrator remained frighteningly elusive.

This wasn’t the first time that women were brutally killed in the same area, nor was it to be the last. Similar murders dated back to 2008  –  little did we know at the time that these would continue until 2015.

Although several arrests were made over the years, the courts are yet to convict anyone for these murders. Where two cases are concerned, the police were able to pinpoint specific motives the remaining deaths however remained a mystery.

What’s more, the similarities in the gruesome murders led many to speculate that the murders could be linked, and/or could have been the work of a prolific serial killer, although police initially denied a connection between the murders.  

Finally, a suspect arrested in 2011 confessed to three killings. However, when it was discovered that he had a history of psychological trauma, and when his arrest did not put an end to the killings which continued on until 2015, people in the area were left baffled and alarmed.

Following the last murder in September 2015,  police have finally singled out the most potential suspect, who was arrested based on DNA evidence. The suspect is currently being tried for at least seven of the murders.

The murders, and resulting police investigations, have filled many news reports over the years, most of which are currently scattered across the cybersphere. With the assistance of the Police Media Spokesperson and Kahawatte Police OIC Rohan Olugalla, we’ve compiled a timeline of the murders and events that followed, to add better perspective to what might just become the story of Sri Lanka’s first (and hopefully last) convicted serial killer.

  • July 21, 2008 The body of Sellama Mariyamma (56), in Kahawatta is found by village residents. The Judicial Medical Officer’s conclusion is that she had been raped and strangled to death. One suspect is arrested, but the case is postponed in November 2014.
  • November 19, 2008  – Ariyawathie (52) living in Kotakethana, Kahawatta, is killed while on her way to her sister’s residence, and her body buried near the Kotakethana lake. Four suspects are arrested.

  • December 21, 2010  – Heen Menika (88) from Dimbulawala is attacked and killed. She is raped and her body displays deep wounds made by a sharp instrument.

All the victims were single elderly women who lived alone. They were all raped and brutally attacked by a sharp weapon and their bodies were dumped near or in the Kotakethana lake. In early 2011, a suspect was arrested, and he confessed to three killings. Investigations and medical opinions however suggested a history of psychological trauma.

Furthermore, this arrest did not put an end to the mysterious killings, which resumed in April 2011. This time around, the killer had changed his modus operandi, and torched all his victims.

  • January 24, 2011 – Police arrest a 29 year old coconut plucker, who confesses to three murders. He is produced before courts, and later referred to mental health specialists, while being held in remand.

2012 saw a drastic escalation in the amount of murders, and a change in the perpetrator’s methods.

No murders or attempts are recorded in the year 2013. Yet, the only murder to occur in 2014, was not the work of the suspected serial killer. Another suspect was arrested, and the murder was revealed to be the result of a feud between two Kovils in the area.

  • October 22, 2014– The body of J. Thilakarani (31), who was living with a cohabiting partner, is recovered from the Kotakethana lake.

The reason for murder had been a feud between two neighbouring Kovils.
  • November 18, 2014  – One of the suspects arrested in connection with the murder and later released on bail, is found dead in his home. The 50 year old suspect had committed suicide after consuming poison.
