UPDATE 12/19/17 @ 9:40 a.m.

A mother has entered a Kennedy plea of guilty in the deaths of her two children, as well as to the injuries to another one of her kids.

Siera Burgess, of Branchland, entered the plea Tuesday morning to two counts of DUI causing death and one count of child neglect resulting in serious bodily injury.

Burgess was arraigned in March after a crash on Interstate 64 in Cabell County that killed two of her children, 3-year-old Skylor Cooper and 1-year-old Sarah Cooper.

Her other daughter, Madilyn, suffered non-life-threatening injuries.

"People don't sit in my cell at night," Burgess said after the hearing, when asked if she had suffered enough and what she was feeling in her heart.

She was originally indicted on charges of DUI causing death, DUI causing serious bodily injury, child neglect resulting in death and child neglect resulting in serious bodily injury.

According to the criminal complaint, Milton Police found several beer cans in the crash area, including some in Burgess's car and some nearby in the debris field.

An earlier lab report also found drugs in Burgess's system, investigators say. They say it was a benzodiazepine-type drug, like Xanax, which has a relaxing effect.

A later lab report showed that the benzodiazepine found was a false positive.

A Kennedy plea in West Virginia occurs when the defendant doesn't admit the act, but admits the prosecution could like prove the charge.

Prosecutors revealed evidence that would be discussed if the case would've gone to trial.

Assistant prosecutor Sharon Frazier says two people noticed that Burgess was under the influence before the accident.

"Another individual also saw Ms. Burgess at that time and likewise believed Ms. Burgess was not capable of driving safely," Frazier said. "That individual actually followed Ms. Burgess in her vehicle and called 911, attempting to have Ms. Burgess stopped."

Burgess is scheduled to be sentenced in January 2018.

Siera Lenise Burgess, 26, of Branchland, West Virginia, has been hospitalized since the crash happened March 3 on Interstate 64, just east of the Milton exit.

Burgess, who was in a wheelchair during her arraignment, didn't show much emotion to our WSAZ camera.

"I have no idea," she said when asked why she was driving under the influence with her kids in the car. "I don't want to talk about it."

When asked what the last few weeks have been like for her, she replied "difficult."

"I've been working with the Milton Police Department on her levels of intoxication," Cabell County Prosecutor Sean "Corky" Hammers said. "We've already acquired an expert. These levels of intoxication, if any, can't just be determined really quickly, so we're going to do everything we can to make sure we get it right and make sure we know what the evidence is, and if she was intoxicated, exactly how bad she was intoxicated."

Burgess's kids Skylor Cooper, 3, and Sarah Cooper, 1, died at the scene. Her other daughter, 7-year-old Madilyn, is recovering from injuries she suffered.

Police say Madilyn has a broken leg, broken clavicle and is extremely bruised, but is going to be alright "physically."

"Enough evidence has been found to justify the arrest warrants," Milton Police Chief Joe Parsons said in a news release.

Police say Burgess was headed east when she crossed the median and crashed into a truck hauling a camper. A tractor-trailer also was involved. Those drivers were not hurt.

Huntington Police continue to conduct a reconstruction of what Milton Police referred to as a "horrific crash."

Family members say Skylor and Sarah were their entire world and they are dealing with an unimaginable loss.

"For me, it's just pushed me to give me a drive more to make sure that our case is perfect, that the investigation is perfect, that we do everything we possibly can for little Skylor and Sarah and Madilyn and hopefully not only the family, but maybe we can find some closure in doing the best job that we possibly can," Davis said.

The crash happened around the 30 mile marker near Milton around 7 p.m.

According to Milton Police Chief Joe Parsons, Skylor Cooper, 3, and Sarah Cooper, 1, died when the car driven by their mother, Siera L. Burgess, 26, from Branchland, crossed the median for unknown reasons and hit an oncoming truck pulling a camper.

“I spent last night praying and I just couldn't sleep,” said Keith. “I just wish that this hadn't have happened. Because I know how much her children mean to her.”

Burgess was seriously injured and is listed in critical condition at a Huntington hospital.

Burgess' seven-year-old child was also hurt in the crash and was taken to Cabell Huntington Hospital.

No one in the truck or tractor trailer were injured.

“I can’t think of anything worse,” said Keith. Keith says when she heard the news of the crash she tried to find out if the news was true, but regardless of who was involved she prayed for their safety.

“My takeaway is, and what I’m going to try to impart to her and her family is, that even in catastrophe we have to keep hope alive and we have to keep fighting and we have to find something positive out of even tragedy.”

Parsons says while the investigation is not complete, alcohol and drug impairment are being investigated as contributing factors in the crash.
