Teen avoids prison time in sister's 'Mortal Kombat' death

Story here. Excerpt:

'Seventeen-year-old Heather Trujillo was given an 18-year suspended sentence in the death of [her sister] 7-year-old Zoe Garcia. However, she must spend six years in the youth offender program. If she does not violate the terms of her plea deal, she will not have to spend any time in prison.

Trujillo will be sent to a facility in Pueblo, where she will stay until her six-year sentence is complete.
...
Trujillo and her boyfriend, 17-year-old Lamar Roberts, told police they were acting out the video game "Mortal Kombat," when they kicked, karate chopped and body slammed the little girl in December 2007. Garcia later died of her injuries.
...
Heather Trujillo pleaded guilty in the death of Garcia in May and agreed to testify against Roberts.'

Two perps: one female (and white), one male (and black). One gets no jail time in exchange for turning on the other. What sort of punishment do you suppose he'll get? What sort of "deal" would he have gotten had he been the one willing to do the talking instead of her?

They both deserve time in jail. For being so reckless and with such a young victim, I think 20 (no parole) might be about right. But only one, it seems is likely to ever see the inside of a cell.
