Police arrested a Coralville woman Wednesday alleging that she intentionally set a fire that killed a 14-year-old boy.

Lillie Will Williams, 49, 419 10th Ave., was charged Wednesday with first-degree murder, a Class A felony.

According to a release from Coralville police, Raymone Bryant, the victim, died of heat and smoke inhalation following a Sept. 4 house fire at an 11th Avenue residence.

The release said Williams was identified by a witness as the person who started the fire. The release also said she was aware people were home when she started it.

Two other victims were transported to the University of Iowa Hospitals and Clinics following the incident, and they were later released.

Williams is being held at the Johnson County Jail on a $1 million bond.

First-degree murder is punishable by life in prison.
