Coming up, the prosecution makes its case against a college football player on trial for murdering his teammate 20 years ago, but has too much time passed?

On the night before Halloween in 1975, 15-year-old Martha Moxley was murdered, but police failed to make an arrest.

Until, in 2000, her one-time neighbor, Michael Skakel, was arrested.

He was also a cousin of the Kennedys.

The Kennedy connection is the reason that most people know about this case.

But the deeper I dug, the more I came to question everything I thought I knew.

Welcome to Ashfield Place.

The safest, safest, safest town in America.

There have been whispers of murder, murder, murder.

For our next story, we're back at the Miami-Dade County Courthouse.

It's week two in the murder trial of Rashawn Jones, a former University of Miami football player.

Prosecutors say nearly 20 years ago, Jones was so consumed by jealousy of his more successful teammate, Brian Pata, that he ambushed him in the parking lot of Brian's off-campus apartment and shot him dead.

Brian's roommate found his body and called 911.

They say one of Brian's neighbors heard what sounded like a gunshot and then saw a man walking briskly past him, a man he later identified as Rashawn Jones.

On Monday, the jury got to hear from that eyewitness, only he didn't show up in person.

Because of his age and failing memory, the jury watched a video recording of his testimony instead.

Here to walk us through what happened and how the defense is pushing back on all of this is Dateline producer Jay Young, who has been in the courtroom.

Jay, thanks for being here.
