The Murder of Sister Abhaya

Sister Abhaya, a young Catholic nun and student, was found dead in a well inside the St Pius X Convent compound in Kottayam on March 27, 1992. Local investigators initially treated the death as suicide. The case later moved to the Central Bureau of Investigation and became one of Kerala's longest-running criminal proceedings.

From suicide theory to a homicide prosecution

Kerala Police and the state Crime Branch initially concluded that Abhaya had died by suicide. After sustained legal challenges, the CBI took over the matter. Over the years the agency submitted closure reports, courts ordered further investigation, and the theory of the case changed substantially.

The eventual CBI prosecution alleged that Abhaya unexpectedly encountered Thomas Kottoor and Sister Sephy inside the convent and was killed to prevent disclosure of what she had seen. That account was the prosecution's theory; it should not be confused with an independently observed fact.

The defendants and the trial

The CBI arrested Catholic priest Thomas Kottoor, Sister Sephy and another priest, Jose Puthrikkayil, in 2008. Puthrikkayil was later discharged before trial for lack of sufficient evidence. The trial against Kottoor and Sephy began in 2019.

On December 22, 2020, a special CBI court in Thiruvananthapuram found Kottoor and Sephy guilty of murder and destruction of evidence. The following day both received life sentences; Kottoor also received a separate life sentence for house-trespass with intent to commit an offence punishable with death. The sentences were ordered to run concurrently.

The evidence was contested

The prosecution case relied on circumstantial evidence and witness testimony accumulated over many years. Several prosecution witnesses turned hostile. The trial court accepted enough of the remaining evidence to convict, but the defence challenged the reliability of key witnesses, the interpretation of medical evidence and the inferences drawn from the scene.

Those disputes became central on appeal. This matters editorially because the existence of a trial conviction does not erase the defendants' right to challenge it, and an appeal is not the same thing as an acquittal.

Kerala High Court suspends the sentences

Kottoor and Sephy appealed their convictions. On June 23, 2022, the Kerala High Court suspended execution of their life sentences and granted bail pending disposal of those appeals. In its interim assessment, the High Court identified evidentiary issues serious enough to justify release while making clear that it was not finally deciding the appeals at that stage.

The suspension of sentence did not itself overturn the 2020 convictions. In the sources reviewed for this file, no later merits judgment finally disposing of those criminal appeals was located.

Current status

The case has a documented trial conviction for murder, but the convictions are under appellate challenge and the High Court suspended the sentences pending those appeals. Crime by Region therefore classifies the file as Solved / Trial conviction under appeal, not as a final, unappealable adjudication.
