A Florida judge has issued a temporary injunction against the husband of the North Charleston woman accused of trying to kill her three children by driving into the ocean at Daytona Beach.

The Daytona Beach News-Journal reported that a circuit judge issued the injunction Monday against 31-year-old Lutful Ronjon of North Charleston, saying that Ebony Wilkerson's sister Jessica Harrell and her immediate family are in danger of repeat violence.

In court documents, Harrell said Ronjon threatened to kill her and her sister if she tried to help the woman escape his abuse.

Records show the injunction against Ronjon is in effect until March 20, when a hearing is scheduled. The injunction orders him to stay away from Harrell, her house, her child's school and a residence where the family is staying.

On Saturday, a judge set bail at $1.2 million for Wilkerson, 32, of North Charleston. She faces three counts of first-degree attempted murder and three counts of child abuse with great harm.

Authorities have accused Wilkerson, who is pregnant, of intentionally driving into the ocean March 4 with her three children - ages 3, 9 and 10 - strapped in the van.

"She definitely tried to kill her children," Volusia County Sheriff Ben Johnson said last week, though he added that the woman had denied the accusation. "She said she was trying to drive out of the water."

Witness statements made to investigators indicated that Wilkerson drove into the ocean with purpose. She tried to ward off those who tried to rescue the children, according to an incident report.

The children were later released into the state's protective custody, according to Florida's Department of Children and Families officials.

While being evaluated at a Halifax hospital, Wilkerson told an investigator she had endured 14 years of agony with her husband, affidavits released by the Sheriff's Office stated.

Ronjon attacked her March 1 while they stayed at a hotel in Myrtle Beach, Wilkerson told North Charleston police two days before arriving at Daytona Beach.

Her husband has not been charged in that incident.
