THE murder of a Knowsley Council environmental health worker Ashley Dale is being featured in a Channel 4 documentary being screened this week.

Environmental health worker at Knowsley Council Ashley Dale was killed when gunman James Witham, 41, forced his way into her home in Old Swan, Liverpool, in the early hours of August 21 last year and opened fire with a Skorpion submachine gun.

The four-part series, titled Merseyside Detectives: The Murders of Ashley and Olivia, focuses on the high-profile murders of 28-year-old Ashley Dale and nine-year-old Olivia Pratt-Korbel, who were both killed in Liverpool in 2022.

Gunman stayed in St Helens after murder

Connections to St Helens were revealed during the court case last autumn.

The trial at Liverpool Crown Court heard that Witham and Joseph Peers, 29, said to be a “foot soldier” who drove Witham to the scene, had both stayed at the Mercure Hotel in St Helens, after the shooting, from August 21 to 23.

At the trial, Peers said Witham had come to his house, on Woodlands Road in Roby, on the morning of August 21 and asked if he wanted to go for a “steam and sauna”.

The court heard Peers and Witham stayed at the hotel in St Helens for two nights, leaving for a few hours on August 22 when Peers said they went to KFC.

On August 23 they checked out of the hotel and Peers said he returned home but later that day Witham asked him to arrange a lift to Scotland.
