A Michigan couple who beat their 3-year-old daughter to death in 2015 during a potty training session learned their fate in court on Wednesday.

A judge called Erika Finley, 29, and Khairy Simon, 27, “selfish” as he sentenced them to 15-40 years and 12-40 years, respectively. The pair admitted to killing Kimora Simon, stuffing her body in a backpack, and burying her body near railroad tracks in Flint.

WJRT reported that the toddler’s body was never found.

According to The Detroit News, Khairy claimed in June that he tried to stop Finley as she repeatedly hit Kimora with her fists and an extension cord. He claimed he was unsuccessful because she is much bigger than him.

The couple hid Kimora’s death for a year-and-a-half. In that time, Finley collected  $7,300 worth of welfare checks for the slain toddler, according to WJRT.

Finley pleaded no contest to second-degree murder and other charges while Simon pleaded guilty to second-degree murder and removing a body without permission. They’re both eligible for parole in less than 15 years.

“I want to apologize to everybody that this situation has affected. And, um, it’s a—I ask for forgiveness,” the slain girl’s father said before sentencing.

The news station reported that Kimora’s two surviving brothers are living with a foster family who plans to adopt them.

“I cannot tell you how much I miss my daughter,” the attorney said, reading a letter written by the victim’s mother. “I cannot tell you express how sorry I am to everyone for what has happened during this situation.”
