Leah Croucher’s parents have spent an agonising three years and eight months waiting for answers after their daughter disappeared on 15 February 2019.

Leah, 19, vanished as she walked to work at a finance company and was last seen on CCTV just after 8.15am in Buzzacott Lane, a two-minute drive away from a house in Furzton, Milton Keynes.

But it was only four days ago on Monday, 10 October, when Thames Valley Police (TVP) received a tip-off from a member of the public, that they started searching the property in Loxbeare Drive.

Officers discovered items including a rucksack and personal possessions belonging to Leah.

Human remains were found in the loft.

Officers had visited the house on at least two earlier occasions during the investigation but there was no response.

They dropped a leaflet through the letterbox asking for the occupant to call if they had information.

The force has since changed its investigation from a missing person’s probe to a murder enquiry – as Leah’s parents revealed how their “darkest fears had come true”.

Detectives insisted it is the first time Leah’s disappearance was linked to the address, despite a huge search involving 4,000 house-to-house calls.

Following the latest developments, police have named the prime suspect as convicted sex offender Neil Maxwell, whose body was found on 20 April 2019 after he killed himself.

TVP said on Friday that during the entire investigation to find the teenager, “there has been no direct link between Maxwell and Leah until Monday”.

What have the police done to find Leah since she disappeared?

TVP said on Friday that from the “very outset” of its investigation, the “most experienced and capable detectives, led by a senior investigating officer” were assigned to the case to demonstrate the force’s “determination” to find the 19-year-old.

In a statement released on Friday, Detective Chief Superintendent Ian Hunter insisted “every reasonable line of enquiry” had been pursued “immediately and thoroughly”.

Efforts to locate Leah included:

• Deploying hundreds of officers and staff to search for the teenager
• Reviewing 1,200 hours of CCTV
• Conducting more than 4,000 house-to-house enquiries
• Searching lakes, open land and woodland
• Media appeals and offering rewards for help

Leah’s parents said they believe police could not have done anything differently and thanked them for their efforts.

They have described their ordeal as “one of the most difficult times of our lives”.

Missed opportunities to arrest prime suspect Neil Maxwell

Handyman Maxwell was hired in 2018 to complete some maintenance at the property in Loxbeare Drive, whose owner lives overseas.

Maxwell was the only person with keys to the house, which was unoccupied when police visited to conduct their enquiries into Leah’s disappearance.

Maxwell was previously convicted for sexual offences against women and was wanted in connection with a sexual assault in Newport Pagnell, on the outskirts of Milton Keynes, in November 2018.

The attack was initially reported to Bedfordshire Police on 29 November 2018 before the case was transferred to TVP the following day.

The force made a total of 18 failed attempts to arrest Maxwell – initially at an address in Milton Keynes on 30 November, when he was not present.

A nationwide chase ensued with police trailing the suspect around the country.

Maxwell used false names and changed mobile phone and vehicles

Mr Hunter said in a statement: “Maxwell knew he was wanted in connection with the sexual assault and was travelling across the UK and making concerted efforts to evade arrest, including false names and changing his mobile phone and vehicles.

“He is likely to have known that he would be returning to prison if he was arrested and convicted.”

TVP also shared Maxwell’s name with other forces in December 2018 and launched a public appeal on 4 April 2019 – just over a fortnight before he was found dead.

Mr Hunter added: “In April 2019, when we published our wanted appeal regarding Maxwell in connection with the sexual assault in Newport Pagnell, and during our entire investigation to find Leah, there has been no direct link between Maxwell and Leah until Monday this week when we were called about the property in Loxbeare Drive.

“If Maxwell were alive today, we would be seeking his arrest in connection with this investigation, so he could be interviewed under caution to provide his account.”

“Whilst Maxwell has been nominated as a suspect, this does not mean he is guilty of any offence,” Mr Hunter added.

He vowed the force would keep an “open mind” as the investigation continues in the hope of “establishing the truth”.
