A new e-fit of the prime suspect in the murder of Leah Croucher has been released as detectives try to confirm that he killed the 19-year-old.

Neil Maxwell, a sex offender who killed himself while on the run from police, died in April 2019 – two months after Ms Croucher vanished.

Officers from Thames Valley Police believe he murdered the Bucks teenager but have been unable to find anyone who can place him near the house where her body was found last year.

They believe he lost weight and grew a beard in order to change his appearance and avoid capture for a previous suspected sexual assault.

Bucks Free Press:

Maxwell was wanted for the sex attack in Newport Pagnell in November 2018, and used false names to evade arrest, as well as stopping using his phone and car.

He was the only person with keys to the house in Loxbeare Drive, Furzton, Milton Keynes, where Ms Croucher’s body was found in October last year after a tip-off from a member of the public.

Detective Chief Superintendent Ian Hunter said: “I can confirm that Neil Maxwell remains the only nominated suspect at this point of the investigation, and our investigation continues to diligently gather sufficient evidence to establish the truth.

“Maxwell knew he was wanted in connection with a sexual assault investigation that occurred in Newport Pagnell in November 2018 and appears to have made extensive efforts to evade arrest by using false names, and we believe he stopped using his mobile phone and his vehicles. He is likely to have known that he would be returning to prison if he was arrested and convicted.

“The investigation has now also established that Maxwell is likely to have changed his appearance to avoid being recognised. He had grown a beard and may have lost weight.

“We have therefore generated a computer image of how Maxwell may have looked around the time Leah went missing in the hope that it may jog someone’s memory. Did you see this person in or around Loxbeare Drive, Furzton, at any time between December 2018 and 20 April 2019?

Bucks Free Press:

“Or can you help us with obtaining further information about Neil Maxwell. Do you know where he was between December 2018 and 20 April 2019, what phone number he was using, what vehicle he was driving, who he was with or any other useful information that can help us establish the truth for Leah’s family?”

Ms Croucher’s body was found at the house less than half a mile from where she was last seen when she vanished while walking to work in February 2019.

No trace was found of the teenager for more than three years despite a massive search operation.

Investigators have so far been unable to find anyone who saw Maxwell in or around Milton Keynes since early December 2018, or near the house in Loxbeare Drive at the time of Ms Croucher’s disappearance in February the following year.
