Two Pennsylvania women have been accused of assaulting an expectant mother and her unborn child in a violent attack, KDKA-TV reports.

Authorities said Kimberly Hopf, 26, and Stefania Bishop, 27, assaulted the victim — Hopf’s sister — while she was in the shower early Friday, at her father’s Penn Hills home.

The victim, Kori Hopf, who is one month pregnant, protected herself and the unborn child during the brutal assault by curling up in a fetal position, according to police. Police arrested Kimberly Hopf in connection with the assault, while Bishop remains on the lam; a warrant is out for her arrest.

“The officers responded to the address and found the victim alone in the home. She stated to police that she was in the shower and was attacked by her sister and a friend of her sisters,” said Howard Burton, chief of the Penn Hills Police Department.

The victim told investigators that her sister was attempting to kick her in the stomach.

“You don’t deserve to have a baby,” Kimberly Hopf allegedly said to her sister, adding, “I’m not going to be an aunt to your child.”

As that was happening, Bishop was allegedly punching the victim in the head and face, according to Burton. Kori Hopf declined medical treatment, believing that the child wasn’t injured because her injuries were to her shins and not the stomach area, police said.

“Fortunately, the victim curled up in the fetal position, protecting her unborn child,” Burton said. “So she did not receive any blows to the stomach.”
