A Hastings woman whose 9-year-old son is charged with fatally shooting his 4-year-old brother has pleaded no contest to a child abuse charge.

Court records say 30-year-old Amanda Pecor was convicted on Monday of felony negligent child abuse resulting in injury. Prosecutors had lowered the charge from felony negligent child abuse resulting in death. Her sentencing is scheduled for Oct. 28.

Her 31-year-old boyfriend, Matthew Edwards, has also pleaded guilty to felony negligent child abuse resulting in injury. His sentencing is set for Sept. 22.

Her older son is accused of shooting his brother, Beau Pecor, with a .22-caliber rifle in April and has been charged with manslaughter.
