Tributes have been paid to retired detective superintendent PJ Browne, who has died at the age of 62.
The garda was one of the most experienced criminal investigators in the garda force.
He held a number of senior posts up to his retirement in 2009 following a 35-year career in the force.
During the 1980s he was a member of the investigation section, known popularly at the time as 'the murder squad', and based at garda headquarters in the Phoenix Park.
In that role he was heavily involved in investigating most of the major crimes across the nation and the squad had a high success rate.
He was subsequently placed in charge of the fledgling anti-racketeering unit at headquarters and then became the senior detective in the fight against crime in the Dublin south central division.
A native of Listowel, Co Kerry, Mr Browne spent most of his career in Dublin.
After his retirement, he worked as a crime analyst with 'The Herald'.
INM Editor-in-Chief Stephen Rae said: "PJ was one of a kind. He was an excellent crime analyst for 'The Herald', unafraid to criticise the force and incisive in his commentary.
"He and his old colleague and friend Gerry O'Carroll blazed a trail on this island as cop turned commentator."
Mr Browne is survived by his wife Ann, daughters Yvonne and Patricia, and son Eoin.
