UPDATE WEDNESDAY: Family and friends of two young Toowoomba men killed in a ute crash near Agnes Water yesterday morning are reeling as they try to come to terms with the tragedy.
The 18-year-old driver and his 20-year-old passenger were pronounced dead at the scene of Tuesday's crash, about 20km from Agnes Water at Captain Ck.
They were driving north on Round Hill Rd in a four-wheel-drive ute bearing the logo of Toowoomba home removal business Hassall Free Homes.
A staff member from Hassall Free Homes yesterday declined to comment.
Police believe the ute veered onto the wrong side of the road before crashing into a drain shortly after 6am.
Agnes Water police officer-in-charge Sergeant John Edwards said officers were working to determine the cause of the crash.
