MACON, Ga. (AP) — A woman charged with murder and child cruelty after three of her four children died in house fire has been granted $75,000 bond.

Colethia Williams, of Macon, is ordered to have no unsupervised contact with children, and will be limited to seeing her surviving child three times a week for two hours during each visit if she's released.

Williams initially said she was returning from a nearby convenience store at the time of the late-February fire, and later said she was at her boyfriend's house. Williams' attorney, Reza Sedghi, says the man lived about a block away from her.

District Attorney David Cooke tells The Telegraph of Macon (http://bit.ly/YyycDx) one of the children had a history of playing with lighters. Authorities have not determined the cause of the fire.
