“Seth stated ‘she’s right next to me — she’s not doing good.’ Seth told dispatch he stabbed Mallory in ‘the neck, the chest, arm a couple times,”” the detective said.

He stated to the dispatcher he stabbed her in the neck first because he “wanted it to take less time,” prosecutors said. In an interview with detectives, he recalled after he stabbed her he remembered her saying “baby, baby, baby, I’m dying. Baby I’m dying. Call the cops.” He also allegedly said he had fantasized about killing Myers with a knife “early on in their relationship,” prosecutors allege.
