It was a summer morning last July when 64-year-old Mairi Morrison set out for her daily walk, not knowing it would be her last.⁠ ⁠ Surveillance video shows a USPS mail truck pulling out of a gas station in Kensington, Maryland, right as Morrison was crossing the driveway.⁠ ⁠ After the USPS driver hit Morrison, he kept driving forward for 4 seconds and then backed up for 6 seconds, all with her body still underneath the van, according to court documents.⁠ ⁠ Now, that driver has been charged with criminally negligent manslaughter, a misdemeanor.⁠ ⁠ Learn more at the link in bio.⁠ ⁠ #uspsdriver #montgomerycounty #maryland #crime #courts
