Arizona Authorities Search for Missing Woman Authorities in suburban Phoenix are conducting a large-scale search for a 19-year-old woman who has been missing for two weeks. Tempe Police Sgt. Mike Pooley says more than 100 officers from the police department, Maricopa County Sheriff's Office and the FBI began the operation early Saturday near 5th and Hardy Streets. They're looking for Adrienne Salinas. Salinas was last seen around 5 a.m. on June 15. Her vehicle was later found by her father, and it had two flat tires. Family and friends have been passing out fliers in the hope that someone has information. A reward of $8,000 is being offered. Pooley says Saturday's search also included Tempe Town Lake. He says authorities have learned from past disappearance investigations that large-canvass searches are often helpful in providing new and pertinent information.
