Murdered Derry musician Jim Gilchrist
Daryl Quigley (32) was found dead in the Simon Community hostel in Henry Street, Ballymena, on Sunday.

In 2008 Quigley and Daniel Young were found guilty of the manslaughter of the well-known blues musician as he made his way home from a motorcycle club meeting in Derry in 2005.
His remains were found in the River Foyle a day later.
Anthony Fahy was convicted of murder in 2008.
Quigley admitted manslaughter and was sentenced to 10 years in prison in 2008 but was freed in 2011.
