Three family members connected to the brutal beating of a pregnant teenager who was raped and forced to miscarry her baby pleaded guilty to the crime and were sentenced to prison this week.

Sharon Jones, 47, was sentenced to 12 years, while her daughter Cecila McDonald, 28, got seven years, and 29-year-old son, Cedric Jones Jr., was sentenced to five years in prison.

Each pleaded guilty to felony family violence aggravated assault.

Another man, Lonnell McDonald, was convicted of aggravated assault in 2016 and sentenced to 10 years in prison in connection with the 2013 assault.

The victim, now 19, reported the attack in 2015.

The girl's brother, 24-year-old Robert Cayald, faces an aggravated sexual assault charge in the case. He was found incompetent to stand trial last year, and his case is pending.

Cayald is accused of raping his 13-year-old sister in August 2012. She became pregnant from the attack. When her relatives learned she was eight months' pregnant, they forced her to take birth control pills and cinnamon tablets to try to abort the baby.

When that didn't work, they held down the teen and took turns stomping on her pregnant belly.

During the attack, Cecila McDonald yelled at the teen, "Bitch, you ain't about to get my kids taken away from me."

The teen and her younger sister had been sent to Dallas after their grandmother died to live with their aunt, Sharon Jones.

The girl was taken in "by people who promised to take care of her," prosecutor Rachel Burris said during the sentencing hearing. Judge Gary Stephens sentenced the trio.

"They held her down. They forced her to lay there while people stomped her," Burris argued. "I️t was savage."

They left the teen in a bathtub, where she lay bleeding, slipping in and out of consciousness, while her younger sister tried to care for her.

No one took her to the hospital or to visit a doctor. To treat the blood loss, the family gave her iron pills.

"She lost a child, and no one cared," Burris said. "That night the people who promised to love her ... left her."

After the teen gave birth in the bathtub, Cecila McDonald put the stillborn baby into a bucket, and the family tried to burn the remains on a grill. When that didn't work, Sharon Jones gave her son $25 to take care of it. He hid the remains in a bag in an unknown location.

Defense attorneys for the trio argued that the attack was a blip in otherwise law-abiding, good lives. They said the brother and sister and their mother were trying to protect their family.

They said the defendants had been part of Bible studies and classes in jail and should be granted leniency.

Defense attorney Regina Clark argued that Sharon Jones, the matriarch, kept her children out of trouble and asked that she be given probation.

"All we heard were positive things about her," Clark said.

Defense attorney Kobby Warren argued that McDonald is an "ideal candidate for a second chance."

He pointed out that she had already spent three years away from her children and was only trying to help her family.

Defense attorney Karen Lambert argued that Cedric Jones Jr. has a low IQ and thought he was helping his family by taking part in the beating.

"Cedric is not what we'd call an independent thinker," Lambert said.

But Burris argued that the defendants merely hid the evil they were capable of.

"Most people would treat strangers better," Burris said. "Yet these people did it to someone they promised to love."
