Three people arrested by gardaí investigating the murder of Marie Kilmartin in the midlands in 1993 have been released without charge and files are being prepared for the Director of Public Prosecutions.
The two men and one woman were detained in Portlaoise Garda station under Section 4 of the Criminal Justice Act.
Ms Kilmartin went missing in 1993. She was last seen alive on the morning of December 17th, 1993, in the Laois shopping centre in Portlaoise.
The search for her turned into a murder hunt when her body was discovered in a bog between Mountmellick and Portarlington on June 10th, 1994.
Three years ago Crimestoppers offered a substantial cash reward for information leading to the identification and prosecution of the perpetrators. A team of gardaí took to the streets of the town in November 2005 handing our circulars in an attempt to jog people's memories on the events that led to Ms Kilmartin's death.
