A teenager who killed her mother last year testified Thursday that her boyfriend threatened to break up with her if she didn't do it.

The boyfriend, 19-year-old Eddie Wayne Chewning, is on trial in Stafford Circuit Court for his role in the July 5 slaying of 62-year-old Brenda Dye.

Dye was killed with a shotgun inside her home on Perry Road in southern Stafford. Ashleigh Nicole Dye, her daughter, has already pleaded guilty to first-degree murder and a firearms charge.

Ashleigh Dye is 18 but was 17 at the time of the slaying.

Chewning is charged with being an accessory to first-degree murder and using a firearm in the commission of a felony. His jury trial started Wednesday and is expected to wrap up today.

Ashleigh Dye, who is in the Rappahannock Regional Jail awaiting sentencing next month, was called as a "hostile" witness by defense attorneys Robin Krueger and Jim Ilijevich.

Most of her testimony was detrimental to her former boyfriend, but the defense apparently wanted the jury to hear her early statements in which she claimed Chewning had nothing to do with the slaying.

"Now you've changed your mind," Krueger said to Dye at one point.

"Now I'm telling the truth," Dye responded.

According to the evidence, Dye and Chewning had been dating about seven months when Brenda Dye was killed.

Both in taped interviews described Brenda Dye as "nagging" and disapproving of their relationship.

Ashleigh Dye said that about two weeks prior to the slaying, her mother caused her to miscarry by hitting her in the stomach.

Prosecutors Michael Hardiman and Ed Lustig pointed out that there are no medical records indicating that Dye was ever pregnant.

The final straw, Ashleigh Dye said in the taped interviews, came when her mother told her she wished she'd been aborted.

Shortly before the slaying, Dye said, she hatched what she described as KBM--"Kill B---- Mom."

She said she and Chewning stopped in a church parking lot late July 4 to plan the killing.

She said Chewning gave her several options, including slitting her mother's throat and cutting her into small pieces and disposing of them.

The miscarriage and Brenda Dye's supposed interference in their relationship were reasons cited for the plan.
