Close on the heels of attacks on churches in different parts of the country, two missionaries were found murdered at their hermitage in Dehradun on Monday morning.

Sixty-year-old Father Samuel and Sister Mercy, 35, were found dead in separate rooms at their ashram 'Samarpanalaya' at Chhota Rampur, police said.

Preliminary investigations showed both were strangulated, they said adding their bodies had been sent for post-mortem to ascertain the exact cause of the death.

The bodies, tied with ropes, were found by a watchman of the hermitage who immediately informed the police.

All the belongings in the two rooms were found scattered, the police said adding, this might have been done to mislead investigators.
