On 30 November 1997, Costello O'Shaughnessy began work at 8am. At 8pm she contacted her taxi base and said she was taking a fare to
Claregalway. About 20 minutes later the base attempted to contact her about a fare but got no reply. Costello O'Shaughnessy was due to meet the taxi owner at 9pm on Dyke Road, Galway, to hand over the taxi and keys so that he could take over the night shift, but she did not show up. He made unsuccessful attempts to contact her. After Costello O'Shaughnessy could not be contacted, a number of taxi drivers in Galway began searching for her and her taxi, a silver
Toyota Carina license plate number 97-G-6663. The taxi was soon discovered at Lydon House Bakery on the Tuam Road in Galway. Hair and blood were found within the vehicle and there had been an attempt to rip out the
taxi meter. The taxi meter read 17 miles, the exact distance from Galway city center to the body dump site and back to where the car was dumped. A search for Costello O'Shaughnessy began and her body was discovered shortly before midday following day, 1 December 1997, on Tinkers Lane, Knockdoemore. She had been badly beaten. == Investigation ==
