Dorset Police received a report at 7.30pm on Wednesday 7 April 2021 raising concern for the welfare of the occupants of an address in Higher Langham.
Officers attended the address and found a man aged in his 80s and a woman aged in her 60s, both with serious injuries. It is believed both had sustained stab wounds.

The injured woman was airlifted to Southmead Hospital in Bristol, where she remains in a critical condition.
Their family has been informed and the coroner has been notified of the death.
Following fast-time enquiries by officers, a vehicle believed to be linked to the incident was located travelling eastbound on the A303. With support from colleagues at Wiltshire Police, Hampshire Constabulary, Thames Valley Police, Surrey Police and the Metropolitan Police, the vehicle was subsequently stopped in the Hammersmith area of London.
