Cornelius told authorities his train had arrived at 2.57 p.m.

and he had driven to her apartment.

He had it down to the minute.

Detectives drove him from the crime scene to headquarters to answer more questions.

So before you walk into that interview room with Cornelius Green,

Biondalino says Cornelius was respectful but standoffish in the interview room.

And when Cornelius was questioned about his car, a 2013 white Kia Optima, he appeared agitated.

Cornelius explained to investigators that he had loaned his car while he was away to a man named Phillip Cutler, who had been visiting from Oklahoma.

Cutler was originally from St.

Louis.

Investigators say once Cutler dropped the car off with Cornelius, the two went their separate ways.

Cornelius was questioned for two hours.

Before he left the police station, he made a call to Philip Cutler.

It seems Cornelius didn't realize the camera was still rolling and the microphone was hot.

Then Cornelius called a woman named Stephanie about his car keys.

And what does he say to her?

Where he at?

He's gonna meet up with you.

Uniformed police officers stopped Stephanie and Philip Cutler near the Amoco station and took them to police headquarters for questioning.

As it turns out, Stephanie had known Cutler for years.
