TODAY marks four weeks since Sunderland grandad Robert Hutchinson was last seen.
The 57-year-old was last sighted at 6.20pm on Monday, June 23, leaving his home in Corporation Road in Hendon.
He left in his car - a blue Nissan Micra - which was later recovered at the end of Stewart Street, just off Chester Road.
Last week, two men, aged 55 and 39 were questioned on suspicion of murder and have since been released on police bail pending further enquiries.
A team of detectives has been carrying out extensive enquiries into Mr Hutchinson’s disappearance.
As part of the investigation hours of CCTV has been viewed and numerous people have been spoken to.
Senior investigating officer, Detective chief inspector Nicola Musgrove, said: “Robert was a dedicated family man and a doting grandfather, he visited his grandson most days as well as spending time visiting other friends and family.
“This is an exceptionally difficult time for his family who are desperate to know what has happened to him.
“It is crucial people who have information now come forward.
“Someone must have information, and I would ask those people to think about how they would feel if this was their family member - a grandson is missing his grandfather, a son and daughter are missing their father.
“I believe there are people within the community who will have information that will assist the enquiry and I would urge those people to come forward.
“We don’t know what happened to Robert or where he is now. How did his vehicle come to be in Stewart Street?
“We know Robert left his home on Monday, June 23, at 6.20pm in his car, the car was later found parked at the end of Stewart Street, just off Chester Road.
“If anyone saw him, either leaving his home or in Stewart Street or saw the car or the car being parked in Stewart Street, we want to hear from them.”
