A former child welfare worker at the center of the Rilya Wilson case took the stand on Tuesday in the trial of Geralyn Graham.
Graham is charged with the first-degree murder of the 4-year-old foster child, who was in Graham's care when she disappeared.
Deborah Muskelly was Rilya's caseworker who was supposed to do monthly checkups. Muskelly did not visit Graham's home for more than a year and filed false reports that said Rilya was in good condition, but the child was missing.
Muskelly testified that when she did make visits to see the child, she never witnessed any "affection" toward Rilya by the child's foster mother.
It took more than a year for the state's welfare agency to realize Rilya was missing. Her disappearance led to major overhauls in Florida's child welfare system.
Investigators believe she went missing in late 2000. Rilya's remains have never been found.
