Prosecutors allege that the defendants also made up fake documents about visits and destroyed records to obstruct a federal investigation.
Assistant U.S. Attorney Bea Witzleben said the case was about "protecting children" and providing a "safety net," but that MultiEthnic dropped the ball.
"This is the kind of job you cannot phone in, you have to see the children," she said, adding that otherwise "children can die."
She said that the evidence against Kamuvaka and Manamela was "overwhelming," and that the two repeatedly told caseworkers "to fill in the gaps" when case files were missing progress notes about home visits.
Witzleben said that Murray didn't begin work for MultiEthnic until 2005, but by spring 2006 "he'd jumped right on the bandwagon."
Murray was assigned to the Kelly family in spring 2006 and was supposed to visit at least twice a week, but he allegedly made far fewer visits and created fake records after Danieal died.
Coulibaly admitted during an interview with investigators in November 2007 that she created false progress notes but didn't mention it when she took the stand in her own defense.
Defense attorneys tried to shift the focus to government witnesses, many of whom had cooperation plea agreements or were given immunity from prosecution.
William T. Cannon, Kamuvaka's attorney, said that Kamuvaka was innocent and tried to make sure caseworkers visited families and filed timely progress reports.
He said that her efforts were "undone" by "renegade workers" who missed visits and then made up false records to cover themselves.
Cannon scoffed that MultiEthnic somehow contributed to Danieal's death. "Danieal Kelly was the victim of an uncaring, if not abusive, mother," he said. (Danieal's mother, Andrea Kelly, pleaded guilty last April to third-degree murder and was sentenced to 20 to 40 years in state prison.)
