Adrienne Salinas was last seen at 3 a.m. by her roommates, when she left her apartment to drive to her boyfriends home, said Sgt. Mike Pooley, a Tempe police spokesman.
Police received reports that her car had been involved in a traffic accident at Ash and Rio Salado Parkway, where she hit the median, he said. A passerby tried to help but the vehicle fled the area.
Police found Salinas car about a block from her apartment, with front end damage and two flat tires. The doors were locked, the overnight bag she packed was gone and there were no signs of a struggle.
Salinas sent a text to her boyfriend at 4:47 a.m. that she was going to his apartment, but she never arrived and her phone was turned off at 5:07 a.m.
