On the day of Josie and Noah’s wedding, the body of a young girl is found on the steps of the chapel where the ceremony was to be held. Josie recognizes the girl as the daughter if the woman who assisted her three months earlier and decides to cancel the wedding. Did she do the right thing or could she have moved the ceremony to another location on the property and then proceeded with the investigation?

Even if this girl was a complete stranger, I don't see how the wedding could proceed with all the police who were needed on the case involved in the wedding. I know Josie would not have been able to separate the events or enjoy her wedding.
