TEMPE, Ariz. -- A black cab pulled up to an AMPM in Tempe to pick up Adrienne Salinas, 19, on June 15 around 5:00 a.m.
The cab driver pulled away when Salinas didn’t show up.
For more than a month, detectives with the Tempe Police Department have been trying to find the missing Salinas.
The cab driver's father, Thomas Simon, said some people posted mean comments on social media, speculating Simon's son had something to do with the teenager’s disappearance.
When asked about those comments specifically, Simon said, “I don’t want to repeat those things. They are things that I wouldn't say at the dinner table.”
On Wednesday, 3TV learned Simon's son was ruled out as a suspect in Salinas' case.
Investigators took the cab’s GPS and verified the driver’s route which helped rule him out as a suspect.
“I never thought he was a suspect but it does feel good to have that verified somehow,” said Simon.
“This is just a big mystery to us. Our detectives are working hard to figure this puzzle out to bring Adrienne home,” said sergeant Mike Pooley.
Salinas' story is a bizarre one.
The teen crashed her car in the early morning of June 15 after fighting with her boyfriend, who has also been ruled out as a suspect.
Salinas then walked home where a party was going on at her apartment in Tempe, but none of her roommates saw her.
Around 4:45am on June 15, Salinas texted her boyfriend she was coming over and called a cab to meet her at the AMPM on University and Hardy by her home.
The teen hasn't been heard from since and that weighs heavily on Simon's son's mind.
“He's thought deeply about what could I have done, could I have gotten there sooner, and if I had gotten there five, six minutes sooner would it be a whole different story?” said Simon.
Police want to talk to anyone who was inside the AMPM around 4 a.m-6:00 p.m.
Detectives have not named a suspect in this case.
