A 'significant level of violence' was used during an attack which left an elderly woman dead and her husband in a critical condition in hospital, police say.
Officers have launched a murder investigation following the incident in Station Road, Langwith Junction, at about 9am on Saturday, January 15. Nottinghamshire Police have since refused to rule out a link between the incident and a burglary in Trowell.
Assistant Chief Constable Dave Kirby, for Derbyshire Police, said although the force was not linking any incidents at this stage, they are looking into similar incidents, and confirmed one of their lines of inquiry for the murder investigation is burglary.
