Police investigating the double fatal collision on Shamrock Road are still appealing for the drivers of two cars to come forward.
The crash, between a Honda car and a truck, at around 7.45am on 11 March, near the Stingray Brewery, claimed the lives of 18-year-old Iliana De La Cruz and 22-year-old Angelo Luciano.
Police would like to trace the driver of a white Nissan Sunny which was seen to leave the On the Run gas station just prior to the crash.
They are also looking for the driver of a silver Ford F150 single cab that was heading east along Shamrock Road just before the Honda passed.
The drivers of the vehicles or anyone else who was in the area at the time and saw either the Honda or the truck prior to the collision are asked to contact Sergeant Adrian Barnett on 946-6254 or 926-2204.
Three other drivers identified through CCTV from the On the Run gas station on Shamrock Road have come forward and identified themselves to police.
