More than a week after mother-of-five Rachel Morin was found dead on a popular trail in Maryland, authorities have yet to make any arrests in the investigation into her death. Morin, 37, was last seen heading to the Ma & Pa Trail at around 6pm on 5 August. Her boyfriend reported her missing that night after she failed to return home and her body was found the following day. On Thursday, Harford County Sheriff’s Office said investigators had been made aware of potential witnesses who may have seen Morin on the Ma & Pa Trail in Bel Air on Saturday. The witnesses – either three men, two women and two dogs or two men, three women and two dogs – were urged to come forward. Officials said that these individuals had been identified and were contacted by investigators. A spokesperson for the sheriff’s office told The Independent on Tuesday that the department had increased patrol on the Ma & Pa Trail area to reassure the community in the aftermath of Morin’s tragic death, but noted that there is no perceived threat at this time.
