Two statewide Child Protective Services officials have announced their resignations.

KVUE obtained resignation letters from Director of Field Operations Colleen McCall and Assistant Director of Child Care Licensing Paul Morris.

McCall, who stepped down Tuesday, was head of a division that came under fire following the beating death of 4-year-old Leiliana Wright in Grand Prairie in March. Wright's family said social worker's ignored warnings that Leiliana was in danger. Two CPS workers were fired in the days after her death and another resigned.

A federal judge in December issued a 260-page opinion in December ordering a complete overhaul of CPS, slamming Morris' division. Morris stepped down on Monday.

"It's clear leading CPS is a tough job," said Stephanie Rubin, CEO of Texans Care for Children.

She said the resignations should show lawmakers they need to take action.

"The legislature has to step up and provide CPS with the funding it needs," said Rubin.

Funding that would go toward reducing caseloads, retaining caseworkers, and protecting children. KVUE reported on Monday that the average daily workload for an investigator in the 30-county Austin region is 24 cases.

Morris and McCalls' resignations follow last week's stepping down of a top CPS official in Dallas. The Commissioner of the Texas Department of Family and Protective Services also plans to retire in May.

A CPS spokesperson said the resignations are not the result of a new commissioner cleaning house, rather that the leadership is in the process of developing a transition plan.

CPS and the state's foster care system have been under fire for years, with high profile cases like Colton Turner and Meechaiel Criner.

"The challenges at the agency level are indicative that the legislature has an urgent need to step up," said Rubin.

Rubin is optimistic about the future. With new leadership and two special masters recently hired to fix CPS, Rubin said the agency is on a strong path to reform.
