Two eerie clues into the vanishing of a mum have been disclosed by a petrol station employee. Rachel Booth, 38, was last spotted in the Barnton area of Cheshire on Saturday, July 19, sparking a massive search operation as police voiced "increasing concern for her welfare". Rachel's last known location was captured on CCTV at Sandiway Garage, on the A556, at 3.50am. Cheshire Police suspect she may have been heading to a nearby village and have conducted an underwater search in the vicinity. A Shell petrol station worker has shed further light on two clues linked to Rachel's baffling disappearance. Station attendant Issac Carolan, 19, revealed to The Sun what the mum purchased in the early hours of that fateful Saturday. He said: "I spoke to my colleague who had served her on Saturday morning. She bought milk and wine and jogged from 45 minutes away." Issac further noted: "But it didn't seem weird, she didn't seem disturbed or flustered." On Saturday evening, police confirmed they were "conducting enquiries" in the local village of Oakmere, near Delamere Forest, and the "surrounding area". Police dogs have also been brought in to aid the investigation around the renowned Cheshire beauty spot. Rachel is described as being 5ft 9in tall, slim, with blonde hair, and was likely wearing black leggings and a black top, reports the Mirror . Staff and customers at a Premier store in Barnton, near Rachel's residence, were reportedly left shocked and distressed by her disappearance. Shop employee Raj Kaur, 30, expressed: "She is a lovely clever lady - always coming in here for her parcels. She is very active and very nice - we all liked her." Cheshire Police Superintendent Paul Hughes voiced his growing concern for her wellbeing. He stated: "As part of our investigation, our officers and partner agencies, including the Underwater Search Team and Cheshire Search and Rescue, are conducting enquiries in the Oakmere and surrounding areas where it is believed Rachel travelled to, and we would like to thank local businesses for their patience and understanding while these are currently ongoing. "Investigators are following all lines of enquiry and anyone who has seen Rachel since she was reported missing is asked to contact us. The same goes for anyone who has any information on her whereabouts. We would also like to appeal directly to Rachel to get in touch to let us know you are OK." Wild Shore Delamere, a popular watersports centre in Oakmere, announced its closure to assist police with the search. The business declared on social media that "police have requested that we close the site to aid their investigation". Wild Shore Delamere announced: "Due to ongoing police investigations in the surrounding area, Wildshore Delamere will remain closed tomorrow, Sunday, July 20th. We sincerely apologise for any inconvenience this may cause. "The incident is unrelated to Wild Shore - however, we wish to help as much as possible - so we will be closing the site until further notice.
