Fulton Co, IND. -- ABC57 has obtained the full video of Alyssa Shepherd's interview with police just hours after the fatal bus stop crash in Fulton County in 2018.

Shepherd was charged with three counts of reckless homicide and criminal recklessness after she disregarded a school bus with its stop arm out, killing three siblings and injuring another young boy.

In her interview with police after the accident, she appears calm and collected.

She's even laughing recalling the moments before she made impact.

"I believe I tried stopping and I usually am driving 50 *laughs* or lower," Shepherd said to police.

This weekend marks the three-year anniversary of the crash, when 9-year-old Alivia Stahl and her 6-year-old twin brothers Mason and Xavier Ingle were killed.

When asked when she realized it was a school bus she passed Shepherd had this to say.

"I saw kids and then there was a crash and it happened so fast. And all of a sudden, I'm trying to call and I'm like a horrible wreck and I'm screaming 'I hit kids I hit kids.’ And I'm searching for my phone and that's when I realized that's a bus and that's children."

Michael Schwab, the grandfather of the three children killed, says Shepherd shows no signs of remorse in her interview.

He’s especially troubled by her description of the moment she made impact, killing his grandchildren.

Hear his full interview tonight on ABC57 NightTeam at 10 and 11.
