(NBC News) – Tonight on “Dateline,” when Kathleen Schroll makes a phone call that names her killer right before her death, it leads to the arrest of a father for murder. But two trials and 12 years later, authorities begin to wonder if he was the victim, not the villain.

Here’s a preview of Natalie Morales’s report: 

The two teenagers who’d been with their dad in the van were down at the station in interrogation rooms. Melody was 14.

MELODY BITZER: I. I was just very, very confused and afraid and on the verge of tears. I had zero insight as to what could possibly be happening.

NATALIE MORALES: And, and sitting there for how, how long bef–


Ben, who was 17 then, says he was scared too.

BEN COONES: Eventually two officers came in and started questioning me about where my dad was the night before. What he was wearing what he was doing. What I was doing the night before. And I couldn’t really give ’em too much information, ’cause I hadn’t paid that much attention Not to mention I was already internally panicking and kind of shutting down to try and deal with what had– was goin’ on. I was handcuffed to a chair in a interrogation room by myself for a solid three hours.

It was afternoon when Ben and Melody were returned home.

MARIAH MINKS: Two cop cars pulled up. And they got out. Melody was a ball of tears

DEE COONES: I didn’t know what, still didn’t know what was going on.

Dee says she was completely in the dark until a detective finally laid it all out. Her husband had been arrested for the murders of Kathleen and Carl Schroll.

DEE COONES: they came back with a warrant. And the phrase they used was, “We’re gonna– we gotta toss this house.” And believe me, they tossed the house.

Investigators confiscated computers and looked for guns and ammunition. They also searched Pete’s van for gunshot residue and blood.

NATALIE MORALES: Was there ever a thought in your mind?






Never, because the family says they knew something police did not.
