BETHLEHEM, Pa. -

A woman is facing charges after stabbing her boyfriend with a steak knife moments after she told her two children to leave the room, officials said.

Tiffany E. Sherry stabbed Michael Martinez in the living room of her home at 947 Wyandotte St. in Bethlehem at about 7: 45 p.m. Monday, officials said.

Martinez told police he slapped Sherry, 24, in the buttocks "as a joke" while she was in the kitchen doing the dishes, even though he knew she had sunburn in that area, officials said.

Sherry turned to Martinez holding a large steak knife and followed him into the living room where her two children were, and as she poked Martinez in the chest with the knife, she told the children to leave the room, officials said.

When the children left, Sherry allegedly stabbed Martinez in the right shoulder and upper back, yelling that she was going to kill him, officials said.

Martinez called police after fleeing to his home at 809 Wyandotte St. and was taken to the hospital, officials said.

Sherry was charged with aggravated assault, simple assault, making terroristic threats and reckless endangerment. She was committed to the Northampton County Prison on $25,000 bail, according to court documents.

A preliminary hearing is set for 9 a.m. Aug. 16.
