Prosecutors also allege that despite warning signs, including what has been described as a shrine in the teen's bedroom dedicated to the Parkland shooter, Colin bought his son a gun for Christmas in 2023.

That weapon is alleged to be the same firearm used in the attack.

Gray's defense says he had no knowledge his son was planning a shooting and argues that this is not a case about punishing a parent for a child's independent actions.

The Barrow County District Attorney told jurors in opening statements that this is not about holding parents responsible for everything their children do, but rather what he describes as preventable warning signs and access to weapons.

Colin Gray has been in jail since his arrest the day after the shooting.

The outcome of this trial could have major implications nationwide as prosecutors increasingly test the boundaries of parental liability in school shootings.

That was Savannah Guthrie in an emotional plea posted to her Instagram earlier this week.

She spoke out again publicly as the investigation into her mother Nancy Guthrie's disappearance intensified.

The message came just a day before the FBI released new evidence, a video showing a possible suspect, and expanded its role, a clear sign that this case has entered a more aggressive phase.

The footage shows a masked figure wearing black latex gloves, carrying a backpack and what appears to be a gun.

The individual seems to be tampering with Nancy's doorbell camera in the hours before she disappeared from the Tucson home she's lived in for over 50 years.

And overnight, another major development.

A man detained near the Mexican border in connection with Nancy Guthrie's abduction has now been released after authorities carried out a court-ordered search of the property where he had been staying in Rio Rico, Arizona.

Delivery driver Carlos Palazuelos was taken into custody following a traffic stop south of Tucson.

He later told reporters he was informed he was being detained for kidnapping, but by early Wednesday morning, he was no longer in custody, and he spoke out to maintain his innocence.
