The operator of a state police photo radar unit was shot to death in his vehicle, which was parked on a north Phoenix freeway to nab speeders.
The shooting occurred just before 9 p.m. Sunday on the Loop 101 and 7th Avenue.
The victim, 51-year-old Doug Georgianni, had worked for three months for RedFlex Traffic Systems Inc. The company has a contract with the Arizona Department of Public Safety to operate photo enforcement vehicles on state highways.
Video equipment on the photo enforcement SUV, which is marked as a DPS vehicle, showed the suspect vehicle was approximately a 1980s model two-tone, gray/white Chevrolet Suburban with a roof rack. The driver is described as a man who appears to be in his 60s, is white and has white hair and a white mustache.
