A man who killed six people, including a mother and four children, has been sentenced to life in prison.

Febrio De-Zoysa, a 20-year-old student, was living with the family in March 2024 when he fatally stabbed Darshani Ekanayake, 35, and her four children: Inuka, seven; Ashwini, four; Ranaya, three; and two-month old baby Kelly.

A family friend, 40-year-old Gamini Amarakoon, was also killed, while the father Dhanushka Wickramasinghe was wounded.

Delivering the verdict on Thursday, Justice Kevin Phillips condemned De-Zoysa's "stupefying, monstrous" actions. "You are the stuff of nightmares... You have caused so much loss and grief," he said.
