From what I heard, they arrested the person in Orange Walk but he has not been charged. However, this case has not been closed yet until they come to an ultimatum with their investigations and charge the person accordingly.
Below is an excerpt from this week's San Pedro Sun newspaper:

Over the weekend, Orange Walk Police arrested a suspect wanted in connection with Young’s murder. According to Inspector Selvin Tillet of the Orange Walk Police Formation, based on a wanted poster circulated by the Caye Caulker police, officers spotted and arrested Edgar Coronado also known as “Campari” for questioning. Coronado was arrested last Friday night on Main Street in front of the Scotia Bank in Orange Walk Town and escorted to Caye Caulker. On Wednesday, October 13th, the Officer in Charge of the Caye Caulker Police Station, Sergeant Dirk Dyer explained to The Sun that even though they have detained Coronado for questioning, he could not confirm whether Coronado would be charged for the murder. When asked why, Sergeant Dyers stated that Coronado is just one of two main suspects and investigation into the murder continues.
