Updated:ROCKDALE COUNTY, Ga. —
Channel 2 Action News has learned of a possible plea deal for one of the teenaged twins accused of killing their mother.
Family members told Channel 2's Rachel Stockman that Tasmiyah Whitehead plans to take a plea deal Thursday.
Stockman sat down with the girls' grandmother Wednesday night who gave new insight into a possible motive behind the killing.
"I would have like to have seen a trial at this point. I will never know, I will never know," said Lynda Whitehead.
She wants her granddaughters, Jasmiyah and Tasmiyah Whitehead, to both stand trial
in the slaying of her daughter, their mother, Nicki Whitehead.
"My child was stabbed 50-60 times and was brutally killed and you offer someone 30 years with parole?" Whitehead said.
Whitehead said she was told by the Rockdale County District Attorney on Wednesday that a plea deal was reached with Tazmiyah Whitehead to charges reduced from murder.
Investigators arrested the twins several months after they discovered the body of their mother brutally beaten and stabbed in a Conyers home in 2010.
"It is like she is not important. She is the victim. It is like no one is concerned with what happened to her," Lynda Whitehead said.
She believes that the twins were upset because their mother was too strict.
"She was concerned about their education. She was concerned about their welfare," Lynda Whitehead said.
But the twin's best friend, Jaleceya Wright, started a Facebook page in support of the sisters saying that there is lot more to the story and turmoil at home.
"I feel like they were a victim of their circumstances more than anything," Wright said.
"Not a day goes by that I don't think of her or miss her," said Lynda Whitehead.
The Rockdale County District Attorney would not confirm that a plea deal has been reached but did say there will be a hearing at 1:30 p.m. Thursday.
As for the other sister, she is scheduled to stand trial on a murder charge in March.
