TEMPE, Ariz. -- It's a text message from 4:40 a.m. on June 15 that Francisco Arteaga can't stop looking at.
Arteaga's 19-year-old girlfriend, Adrienne Salinas, sent a text she was coming over to his house in Scottsdale before going missing in Tempe.
He told 3TV he has no idea where Salinas is.
"That's the hard thing. It makes you go crazy in your head you just don't know what to think," Arteaga said.
Salinas sent that message around the same time she called a cab company, Scottsdale Cab Guy, to pick her up from an ampm convenience store close to her apartment off Brown Street and Hardy Drive.
An hour before sending the text, Salinas crashed her car close to home.
The teen then walked back to her apartment, changed clothes, left and hasn't been seen since.
"Something happened to her. Somebody took her," said Salinas' aunt, Pamela Coss.
"We just buried my son 15 months ago," she said
Coss' 19-year-old son Fabian Cano, was murdered during a drive-by shooting in Phoenix.
The shooter hasn't been caught.
"I'm afraid we're going to be left with memories again. She's 19 and my son was 19 when he was murdered. It's not fair," Coss said.
Salinas' family and boyfriend say she would not run away.
"It had to be foul play," Arteaga said.
The father of the cab driver told 3TV his son has been questioned by police.
Sgt. Mike Pooley with the Tempe Police Department would not comment on that part of the investigation.
The cab driver has told police when he got to the ampm store, Salinas wasn't there.
The FBI has also joined the investigation.
The reward is now at $10,000.
