Police have launched a double murder inquiry after a mother and son were found dead in Coventry.
The body of Julie Williams, 58, was found at her home on Sunday. Her son David Williams was found at a nearby property on Monday night.
Police say they believe Anthony Russell, 28, is responsible.
The West Midlands force released an image of Mr Russell as part of its manhunt, and described him as dangerous.
Mr Williams's body was found at a flat on Riley Square at about 23:30 GMT on Monday.
He was reported missing to police on Saturday, having not been seen since 20 October.
Mrs Williams's body was discovered at her nearby flat, also on Riley Square, just before 23:00 GMT on Sunday after concerns were raised for her welfare.
Police said Mr Russell, of no fixed address, had links to Coventry, and could have travelled to Plymouth, Devon or Cornwall.
The public is asked not to approach him and to dial 999 instead.
A 36-year-old man has been arrested on suspicion of conspiracy to commit murder and is in custody.
