The death of a retired teacher and her son at their residence in Mattannur, Kannur, was a murder followed by suicide, with no involvement of outsiders, police said.
Preliminary investigation established that Naveen Krishna (21) hacked his mother, C. Jyothi (56), to death before taking his own life by stabbing himself in the chest.
The bodies were found at their house, ‘Nandanam’, on Lions Club Road near Mattannur Mahadeva Temple on Tuesday.
Jyothi’s husband, K.T. Jayakrishnan, discovered the bodies when he returned home around 10:30 am after visiting the temple.
Both individuals had sustained severe neck and chest injuries.
Upon hearing Jayakrishnan’s cries, neighbours rushed to the house. The woman and her son were rushed to a private hospital, where they were declared dead on arrival.
The bodies were later shifted to Thalassery Government Hospital for post-mortem procedures.
The cremation is expected to take place on Wednesday.
According to the police, Naveen had been undergoing treatment for severe depression and attended a counselling session at a mental health centre in Kuthuparamba on Monday, a day before the incident.
Police confirmed that preliminary investigations rule out external involvement.
However, authorities added that the case remains open and further investigation is underway.
