ALLENOWN, Pa. -

An Allentown woman accused of killing her boyfriend is pleading guilty to third-degree murder.

Police say Carolina Feliz stabbed 52-year-old Desiderio Morales in the neck after an argument last October.

The attack happened at their home on South 9th Street in Allentown.

Authorities say the 37-year-old Feliz hid a knife under her pillow because she anticipated "having problems" with her boyfriend after drinking with her mother the night before.

Feliz will be sentenced next month.
