(WICHITA, Kan.) -

A mother accused of leaving her kids alone when they started a deadly fire was in court today.

Ruthie Lee Bell is charged with endangering her children. A judge entered a not guilty plea on her behalf this morning.

Prosecutors say her three kids were home alone when her six-year-old daughter picked up a lighter.

Investigators say the girl lit trash on fire, which then ignited her clothes. She died three days later in the hospital.

Bell will be back in court in December.
