MYSTERY surrounds the final hours of a North-East grandmother who plunged from a bridge to her death on the side of the A1M yesterday.

Jean Rees, 61, went missing from her home in Fulthorpe Avenue, Darlington, between Monday night and Tuesday morning.

Early yesterday, a lorry driver travelling on the A1M alerted police about a woman standing on the A67 bridge at Merrybent, about 20ft above the motorway.

When a Durham Police traffic car arrived, officers found Mrs Rees' body on the hard shoulder.

An investigation has been launched to piece together her whereabouts between leaving her home and her death.

It is not believed Mrs Rees had been hit by a vehicle, but a post-mortem examination was still to be carried out. An inquest is expected to be opened soon
