A 16-year-old with learning difficulties who drowned in the River Erne had not been assaulted before he entered the water, a coroner has said.
But the mother of Daniel Mohan still fears that her son may have been beaten up and tossed into the river.
Daniel’s body was recovered from the water adjacent to Willoughby Place in Enniskillen after he was reported missing on April 25, 2010.
His body was found five days later on April 30.
A Police Ombudsman's report led to nine police officers, eight of supervisory rank, being disciplined after they failed to locate Daniel in an “expeditious and thorough manner”.
At yesterday's inquest in Enniskillen, Coroner John Leckey reported that the pathologist found two illicit drugs BZP and TFMPP in Daniel's system, and a low level of the tranquilliser diazepam.
