A doctor with terminal cancer killed a female pediatrician and then himself after taking hostages at a children's clinic in Austin, Texas.

Dr Bharat Narumanchi held hostages in a five-hour siege before killing Dr Katherine Lindley Dodson.

Narumanchi had applied for a volunteer position at the clinic a week ago and was declined.

He later came back carrying a pistol, a shotgun and two duffel bags.

Police spokesman Jeff Greenwalt said Narumanchi had recently been given "weeks to live" after a cancer diagnosis.

He said: "The case as far as who did this is closed. We know who did it. And we know that there's no longer a threat to the public. But we really, really want to answer the question of why."

Dr Lindley Dodson, 43, was beloved by patients and their families. (The Independent, UK)
