Meanwhile, the carriage had been shunted into a siding and examined, which revealed three bullet marks and other signs of a fierce struggle, including blood on the carriage's footboard, mat, and door handle, as well as on a handkerchief and newspaper.
The authorities still saw no reason to detain Mapleton, and he was escorted by Detective Sergeant George Holmes to the home of Mapleton's relatives who ran a boarding house at Cathcart Road in Wallington in Surrey.
