Authorities have released the names of a man and woman killed in a New Year's Day hit-and-run accident in Tucson.
Meanwhile, Tucson police are trying to locate a taxi driver as a potential witness in an investigation into a double homicide.
Police say 32-year-old Patrick Balbastro and 47-year-old Cindy Burnett were fatally injured and another person seriously injured Wednesday morning when they were run over during an altercation.
Police say Balbastro and Burnett got out of a taxi and were approached by the driver of another vehicle. An argument ensued and the driver allegedly ran over three people.
Burnett died at the scene and police say Balbastros later died at a Tucson hospital.
They say Balbastro's 43-year-old girlfriend remains hospitalized with critical injuries. Her name hasn't been released yet.
