Det Chf Supt Judi Heaton: “We are today continuing our investigation into the murder of Shane Gilmer and attempted murder of Shane’s partner Laura Sugden, who is pregnant.
“Laura’s injuries were not life threatening and she and the baby are stable.
“The incident happened in their home in Southburn, Driffield, on Friday evening and we are still actively searching for a suspect.
“What’s really important to us is that we find Anthony Lawrence, who is also known as Tony Howarth, and bring him in safely.
“We want to say thank you to the public for their assistance in our investigation so far. Their information has been invaluable and we’re following up a number of lines of enquiry.
“We have recovered a car linked to him – a blue Vauxhall Mevira – which is being examined by our forensic team.
“We have also recovered a crossbow from the scene and again, this is being forensically examined.
“We still have teams in the Southburn area and they will be remaining in that area for the next few days, both as part of the investigation and to provide reassurance for those living and working there.
“As we’ve said, we don’t believe that Lawrence is a threat to the wider public. This was an isolated incident and he was known to Shane and Laura – they were neighbours.
“However, we don’t know how he will react if challenged, so do not approach him. Call 999 and leave it to us.
“While we are not going to go into the specifics of what we believe happened that night, we do want to correct some misinformation that has been reported about the incident.
“There is no suggestion that Lawrence came in through a cellar – there is no cellar.
“We would welcome any further information from the public.
“He is white, 55-years-old, 5ft 10in tall and balding, with close cropped dark hair.
“Again, if you believe you’ve seen him, don’t approach him. Call us immediately on 999 and let us deal with it.”
Mr Gilmer's family has asked that all media use the photograph issued with this statement and not those taken from social media.
