An Iowa City woman charged with first-degree murder will have a hearing to discuss her request to receive information about a potential witness.

Lillie Will Williams, 49, was charged with first-degree murder in November 2011 after she allegedly started a fire that killed a 14-year-old boy and injured two others, according to a police complaint.

The defense has requested that the competency of a 5-year-old witness be determined. Iowa Code requires a witness to be competent, and the court must determine the competency of a child witness if his or her competency is questioned.

Williams therefore requested the state make available "any and all information, including audio and video recordings… known to law enforcement and the Johnson County Attorney’s office, relating to the witness listed as "a child" in the state’s trial information," according to court documents.

The hearing on Williams’ motion is set for March 2 at 10:30 a.m. in the Johnson County Courthouse.
