The first officer on the scene was Charles Horton. In 1811,


There didn't seem to be a motive. Nothing appeared to have been taken, and money was still left in the till and in several drawers in the home. Perhaps the thief had been scared off before he'd finished what he came for. The other possibility was some sort of revenge, which would indicate that the attacker probably knew Timothy Marr and had a grudge.
Then two sets of footprints were discovered at the back of the shop, and because the tracks proved to contain not only sawdust from work done by a carpenter inside that day but also traces of blood, they appeared to belong to two killers. As citizens followed the tracks, they came across a man who claimed that he had heard a number of people in an unoccupied house next to him. So perhaps there were more than two involved. It now looked like the work of some nefarious gang.
When Horton brought the bloodstained maul back to the police office, he found that three men were already in custody. As James and Critchley indicate, they were sailors who had been seen in the area that night, which was not unusual. One appeared to have spots of blood on his clothing. However, they all had convincing alibis, so they were released. Others were picked up, based on witness reports, and those cases fell apart as well. A small reward of fifty pounds was offered for information and, to notify area residents, a handbill was drafted and stuck on church doors.
A coroner's jury was organized on December 10 with Coroner John Unwin, in which the principal players retold their stories from that fateful night. It seemed evident that someone had been watching the place for the servant girl's departure, as if they knew that she would be sent out—an odd thing for Marr to do at such an hour. And their crime had been committed between 11:55, when she left and 12:15, when she returned.
One idea was to attempt to trace the origin of the maul via the chip in its blade. Perhaps someone knew something about that. Another was to ponder the chisel. While there was no blood on it, Margaret's story indicated that Marr had been looking for such a chisel that very evening and had it been in such plain view, he would have noticed. So perhaps someone brought it in to use as a weapon. In fact, one of the carpenters who had worked in the shop that day was detained, but there was no real case against him, so he'd been released (perhaps too quickly). A previous servant girl who'd been let go was also questioned, but she seemed to lack motive as well as criminal companions, and she was too small to have performed such deeds herself.
The next grim task was to bury the dead.
