Gardai issue witness appeal over the unexplained death of John Hannigan

The 48-year-old died in Dublin on February 20 earlier this year

Gardai have issued a witness appeal in connection with the unexplained death of 48-year-old John Hannigan who died earlier this year in Dublin.

Mr Hannigan was found on February 20 in the hallway of his apartment complex on Grosvenor Road, Rathmines and taken to St James' Hospital where he later passed away.

Post-mortem results of his death are not being released for "operational reasons".

Investigations have led gardai to find out that Mr Hannigan travelled at 1:30pm on January 3, 2020 to Balally in Sandyford to meet a family member for a short time.

However, gardai have been unsuccessful in finding a witness who can provide information on John's movements between the time he left Sandyford on January 3 to when he was found in the hallway of his apartment complex in Rathmines on February 20.

A garda spokesperson said: "Investigating Garda have not been able to determine the sole cause of John's death as being due to natural or accidental circumstances and continue to investigate all the circumstances of this unexplained death.

"Garda are appealing for anyone with information, who has not already come forward, to come forward. Garda are particularly interested in speaking to anyone who may have information on John's movements from New Year period to 20th February 2020.

"Anyone with information is asked to contact Rathmines Garda Station on 01 666 6700 or the Garda Confidential Line on 1800 666 111."
