Salinas was last heard from in the early hours of June 15 after she and her roommates hosted a party at their apartment in Tempe.

Police say the teen was last heard from around 4:30 a.m. that day when she called a friend to say she was coming over, the station reports.

Shainey Duggan, one of Salinas' roommates, tells KPHO Salinas was on her way to visit her boyfriend.

"Her and her boyfriend got into a little argument, and she was going to go to his house," Duggan told the station.

But, the station reports, she never got there. Police say she blew out the two front tires to her car just a couple of blocks away from her apartment. Cell phone records show she called a cab to pick her up at a nearby gas station, but she never made it there either, the station reports.

Salinas was reported missing after her family knew something was wrong when she failed to call her father to wish him a happy Father's Day on June 16.

Police searched Tempe Town Lake, about 5 miles south of Scottsdale, last week as part of their investigation.

"We just wanted to rule out any possibilities of her being in the lake. We obviously didn't find anything," Sgt. Michael Pooley of the Tempe Police Dept. said.

Police say they are hoping someone who knows what happened to Salinas will speak up.

"We're hoping someone saw something," Pooley said.
