NEWARK — In the hours after eight-year-old Christiana Glenn was found dead in an Irvington apartment in May 2011, one of her caregivers, Myriam Janvier, told police how she and the girl's mother would discipline Glenn and her two younger siblings.

Guided by their faith, Janvier said she and the children's mother, Krisla Rezireksyon, would tie the children to radiators and make them kneel on salt. Sometimes the women would delay feeding the children, Janvier said.

"Christ talks to us personally," Janvier, dressed in all white clothing, told the detectives in a videotaped statement. "It's not easy to be a Christian."

Janvier, 27, and Rezireksyon, 33, are facing murder and related charges for allegedly killing Glenn, and abusing and neglecting Rezireksyon's two younger children. Authorities discovered the children in the apartment on May 22, 2011 after Rezireksyon called 911 when Glenn was not breathing.

Authorities have said Glenn was emaciated and had an untreated broken leg, and her siblings - Solomon and Christina Glenn - were also starved and sustained fractures that went untreated.

A portion of the video recording of Janvier's interview was played on Friday during a hearing to determine whether her statement will be admissible at her trial. After similar hearings, Superior Court Judge Michael L. Ravin determined that Rezireksyon's statement will be admissible at her trial.

But the admissibility of Janvier's statement will be based in part on how detectives did not advise Janvier of her Miranda rights until after they had begun speaking with her.

Sgt. Michael Davidson of the Essex County Prosecutor's Office, one of the detectives who interviewed Janvier, testified on Friday that he advised Janvier of her rights after learning during the interview that she had played a greater role in caring for the children.

"To me, it seemed as if the kids had two moms," Davidson said in response to questioning by Essex County Assistant Prosecutor Dawn Simonetti. "At that point in time, I felt that she had more responsibility to the kids than I believed in the beginning."

But on cross-examination, Janvier's attorney, Olubukola Adetula, stressed how Davidson interviewed Rezireksyon before speaking with Janvier.

Given what Rezireksyon had told Davidson, Adetula argued the detective believed Janvier exerted parental authority over the children. If the detective had that impression, Adetula claimed Davidson should have advised Janvier of her Miranda rights at the beginning of their interview.

"Did you not get the impression after you interviewed the mother, natural mother, that Ms. Janvier had some type of control over the kids?" Adetula asked Davidson

Davidson said that after speaking with Rezireksyon, he didn't get the impression that Janvier had the "equal powers" of the children's mother.
