Police say two people who were in custody in Dallas after authorities found a missing baby knew the mother who was shot to death at her Kansas home.

The Wichita Eagle reports that Police Chief Gordon Ramsay says two people were taken into custody before dawn Saturday after authorities found baby Sophia at a Dallas home.

He says the baby, who was six days old when she was reported missing Thursday, is healthy and in protective custody.

The baby’s mother, 27-year-old Laura Abarca-Nogueda, was found shot to death at her home Thursday.

Police spokeswoman Sgt. Nikki Woodrow told The Associated Press that the suspects knew the baby’s mother, but did not provide details, citing the investigation.
