Kansas' child welfare agency says it last had contact in February 2012 with a boy who was murdered and fed to pigs in 2015 but had later contact with other family.

The Department for Children and Families on Tuesday clarified an earlier statement about 7-year-old Adrian Jones and his family. The boy's father and stepmother are in prison for his death in Kansas City, Kansas.

A May 5 statement said the department's last contact with the family was February 2012.

The department said Tuesday it was in contact with the stepmother and other family in December 2012. Records also show a social worker talked to the stepmother by phone in October 2013.

The agency said the father and stepmother were separated in 2012 and Adrian lived with his father.

Newly released document show that Kansas received reports that a boy who ultimately was murdered and fed to pigs was being physically abused years before his death.

Documents also showed Tuesday that a social worker was in contact with his father and stepmother by phone more than a year after the state said it lost physical contact with the family.

The Kansas Department for Children and Families released more than 2,000 pages of documents on Adrian Jones. His father and stepmother are serving life prison sentences in his death. Authorities say Michael and Heather Jones abused, tortured and starved Adrian before his remains were found in Kansas City, Kansas, in November 2015.

Secretary Phyllis Gilmore has said the Kansas agency's last physical contact with the family was in February 2012. But one record shows a social worker talked to the boy's stepmother by phone in October 2013.

The head of Kansas' child-welfare agency says she's "deeply saddened" by the slaying of a 7-year-old boy whose remains were fed to pigs, and that state case workers did what they could.

As director of the Kansas Department for Children and Families, Phyllis Gilmore offered that perspective Tuesday as her agency was releasing roughly 2,000 newly unsealed pages of its casework involving the family of Adrian Jones.

Adrian's remains were found in November 2015 on the family's Kansas City, Kansas, rental property. The boy's stepmother and father have pleaded guilty to murder charges in Adrian's death and are serving life sentences.

Gilmore says Jones' father and stepfather "worked constantly to evade our intervention" by moving between Missouri and Kansas. Gilmore says her agency's last contact with the family in 2012.
