Guilty plea in 'Mortal Kombat' death

GREELEY, Colo. - December 15, 2008 - The Weld County prosecutor's office says 18-year-old Lamar Roberts pleaded guilty Monday to knowingly causing a death through child abuse.

Prosecutors say Roberts and 17-year-old Heather Trujillo were baby-sitting Zoe Garcia a year ago. They say they kicked, hit and slammed the girl to the floor.

Trujillo pleaded guilty in May to negligently causing a death through child abuse. She must complete six years in Colorado's youth offender system.

Sentencing for Roberts is set for January.
