Kottayam Superintendent of Police Shahul Hameed confirmed that all possible angles are being explored, including the potential that the couple’s murder was meant to intimidate or silence.

“The timing cannot be ignored. We are coordinating with the CBI to assess whether there’s any overlap in persons of interest or emerging leads.”

Amit, who had recently been released from prison after serving time for theft at the same residence, is under surveillance.

Police believe the attack was carefully planned, given the missing CCTV footage and signs that the pets were deliberately sedated.

The couple’s daughter is settled in the United States and is expected to reach Kottayam by April 23.

T K Vijayakumar, 70, a prominent businessman and owner of Indraprastham Auditorium in Thirunakkara, and his wife Meera, 67, were found dead inside their home on April 22.
