Marilyn Hampton is alleged to have carried out the attack at the 3500 block of Long Bow Drive in Whitehaven on January 4, according to CBS affiliate WREG.

An affidavit, obtained by the broadcaster, stated the victim had been in an argument with her sister when her aunt, Hampton, stepped in and joined the quarrel.

The victim, who was five months pregnant at the time, alleged that her aunt pushed her over before Hampton’s sons also started to attack her.

According to WREG, the victim claimed in the affidavit that she was “choked, hit, kicked, and knocked down” and that she also had difficulty breathing during the attack.

Memphis Police Department (MPD) officers arrived at Long Bow Drive after the victim called 911, the broadcaster reported.

Following her transfer to a nearby hospital, doctors told her one of her baby’s arms was broken during the attack.

WREG reported Hampton had been expected to appear in court on February 7 on two charges of aggravated assault.

The victim is now in the state’s DeSoto County Jail on charges of disorderly conduct as well as conspiracy to commit a felony crime, according to the broadcaster.

Newsweek has contacted the MPD for comment.

According to legal firm Adrian H. Altshuler and Associates, aggravated assault is defined in Tennessee as “generally a class C or class D felony, depending on the circumstances.”

It said: “The penalties for a misdemeanor are up to 11 months and 29 days and/or a $2,500 fine. The penalties for the felonies can range from two to 15 years and up to $10,000—depending on the class of the felony.

“Additional sentencing factors include the status of the victim such as a police officer or a family member.”

Last month a pregnant woman expecting twins was set on fire by her boyfriend, according to police.

Detroit police said Devonne Marsh, 41, got into an argument with his 26-year-old girlfriend at their home near Packard Street and Outer Drive, on January 14.

Marsh is facing felony charges of assault and bodily harm less than murder and assault with a dangerous weapon, according to online records from the Wayne County Sheriff’s Office.

The woman, who was more than six months pregnant at the time, has serious burns over more than 60 percent of her body.
