Arkansas mom found shot to death with two children wrote cryptic Facebook post months before killings

He received a one-year suspended sentence and was issued a no-contact order for his wife or any of her family members, which Charity approved.

"If a woman's partner has ever strangled her, even once, her risk of being murdered by that same partner with a gun shoots up 750% compared to a woman who has never been strangled," a Daily Press article shared by Charity states.

The wife and mother added a series of hashtags in the comment section of the post, including "#StopCorruption," #JusticeForVictims," #AccountabilityNow," "#SystemicFailure" and more.

According to the outlet, Charity also commented on a 5 News article in August, writing, "I'm living this battle right now. I am the victim, yet I've been treated like the problem while the criminal - a local doctor - is being shielded by the very system that's supposed to protect us.

"I've tried to reach Prosecuting Attorney … but he won't even accept a letter from me. My voice, as the victim, has been shut out," Charity wrote. "This is not just about me - this is about a system that protects offenders and rejects victims. Lives are at stake, including the lives of young children."

The Sebastian County Sheriff's Office wrote in an update on Tuesday that the United States Secret Service and Homeland Security Investigations are now among the agencies involved in the investigation.

A suspect has not been named, deputies added, but they said 12 search warrants are in progress and six have been served.

Randall's attorney told the outlet his client has been cooperative with law enforcement and fully supports the Sebastian County Sheriff's Office investigation.

After Charity died Dec. 4, Randall's attorney filed a motion to dismiss the divorce case. Charity was seeking full custody of the children.
