Garden City police officers say they started looking into a couple suspected of foster abuse after concern from the Kansas Department for Children and Families.
Capt. Randy Ralston said by the time the investigation wrapped up, the alleged victims no longer lived in the home.
"No serious injuries as far as needing medical treatment immediately, because of the time frame from 2008 to now obviously a lot of the injuries have healed and were unreported."
The abuse is said to have occurred over six-year period, from 2008 to 2014, to seven children.
The couple faces multiple child abuse charges. They're scheduled to appear in court later this week.
Two people have been arrested, accused of child abuse, with the crimes dating back six years ago, according to Garden City police.
Police said the child abuse case against foster children began in April. The investigation revealed two women had allegedly abused and mistreated several children who were in foster care in the 1300 block of East Fair. Eight victims, between the ages of 1 to 15 years old, told police the abuse reportedly began in 2008.
Glenda Griffin, 40, and Stacy Griffin, 47, were arrested last week. Glenda faces 9 counts of child abuse and 1 count of child endangerment. Stacy was booked on two counts of child abuse.
The case will be turned over to the Finney County attorney's office for formal charges.
No other details are being released at this time.
