Officers were called to White Lodge Shooting School, College Road, near Thornton Curtis, North Lincolnshire, at about 3.40pm on Friday after reports of a concern for safety. Mr and Mrs Jobson were pronounced dead at the scene.
It has now been claimed Mrs Jobson was shot by her husband after he became angry she had found entered into a relationship with another man.
Reports say the couple separated after Mrs Jobson fell for a man she met at the shooting school.
Next-door neighbour Andrew Farrow senior told MailOnline: “The couple had split up and their school had been closed temporarily for personal reasons because of it.”
Mr Farrow added: “We understand he was jealous and who knows what things go around in people’s brains.
“We assume it was gunshot and that he had shot his wife and then himself.”
Another local, who did not want to be named, said: “The couple had separated last month.
“Rose had a new boyfriend and Rob was fuming when he found out. He couldn’t bear losing his lovely wife to another man. She is a very pretty lady and an accomplished shooter herself.”
Mr and Mrs Jobson purchased White Lodge in 1991 and decided to turn it into a shooting school, according to the couple’s LinkedIn profile.
It says they specialised in clay shooting tuition, but over the years branched out to include corporate entertainment.
The social media post adds: “We are a relaxed, friendly establishment where we can give clients ‘the personal touch’ and an enjoyable day out.
“White Lodge Shooting School is suitable for all levels of experience from the complete beginner to the more advanced shooter with a number of different activites to participate in to make your day with us special.”
Senior investigating officer, Chief Inspector Al Curtis, said: “Both Robert and Rose’s families continue to be supported by specially trained officers as they come to terms with their loss. My thoughts remain with them at this incredibly difficult time.
“Understandably, a tragic incident like this will cause shock amongst the community, and my officers continue to support local residents by conducting house to house visits to offer reassurance and engage with the community as they come to terms with what has happened.
“We can confirm we are not looking for anyone else in relation to their deaths. If anyone has any concerns, please speak to our officers.”
