The sister, who was three-and-a-half months pregnant, went to the hospital for stomach cramping, but her unborn child was unharmed.
Monica Williams, 33, is charged with one felony count of terroristic threats and one third-degree misdemeanor count of assault of an unborn child.
According to the criminal complaint:
On Oct. 9, Williams and her boyfriend's sister got in an argument outside Williams' apartment complex on the 3100 block of Highway 100.
Williams grabbed the sister by the hair and punched her.
“If it’s up to me, you’re not going to have a child,” Williams said, according to the complaint.
The sister said she then felt a strong blow land on her stomach.
A witness told police that she heard Williams tell the sister, "I can’t believe you had the balls to come back here after I threatened you and told you not to come back."
Williams then grabbed the sister by the hair, throwing her to the ground and placing her knee on her stomach, the witness said.
“Your baby is not going to be born," Williams said, according to the witness. "Your baby is not coming out. You’re not having a baby. It’s not going to happen.”
Williams faces up to five years in jail and a $10,000 fine.
