She's out of jail because she is only charged with child endangerment, which is a misdemeanor, and lying to investigators, which is a Class C felony. Forget for a moment that everyone deserves bail, the 500 thousand dollar bond for these particular charges was extremely excessive. In addition, she's under home confinement. This is redundant and almost unheard of. If they had proof she killed her kid and stuck her in the trunk, they would have upped the charges and kept her in jail. The dna testing on the trunk has had plenty of time to be completed, so the fact that they did not up the charges tells me they got nothing.
