A car owned by a man reported missing by his family has been found at the scene of an unexplained death in North Canterbury.

Richard Leman, 41, has been missing for more than a week and multiple social media posts have been shared by his family seeking sightings and information.

This morning police confirmed they were investigating after a body was found at a residential property on Tyler Street in Rangiora.

 “Police were called to the Tyler Street address at 7.40pm yesterday,” said a spokesperson.

 “The person’s death is currently being treated as unexplained and a scene guard was in place overnight.

“Tyler Street residents can expect to see a continued police presence today as officers conduct further enquiries.”

Leman’s sister Kim Leman Bennett posted on Facebook that he was last seen at a shopping centre in Rangiora at 8.20pm on April 11.

Two days ago she said there had been “no new sightings”.

Leman had been staying in the Sefton and Rangiora area.

“Police have been notified… We have grave concerns for his safety and mental health,” his sister posted.

“Someone out there must know something we just need to know and want him home.”

This morning Leman Bennett declined to comment.

She said in her earlier post that Leman “may look rough and tough” but he was “a big baby at heart and a mummy’s boy”.

The fact he had not called his mother in more than a week was concerning because he usually spoke to her every day.

“Our little brother has the kindest heart, loves his children, loves his family and would do anything to help others,” Leman Bennett said.

“We just want him home.”

She then listed the details of his car - which is parked at the property police are focussing their investigation on today.

A Givealittle page had also been set up to help the Leman family with their search for their missing son, brother and dad.

“We couldn’t just sit and do nothing,” said his other sister Nicola Leman on the fundraising page.

“We have taken on the search and any and all information we are providing to the police, but as we all know the police are under-resourced.

“So we are following up on possible sightings from our social media posts, putting out flyers, and searching daily.

“We also need to cover his personal costs until he is found.”
