Jenifer Marie Sierra was not arrested for the death of her baby, but for outstanding warrants and felony child endangerment. There has to be an autopsy done before charges can be brought, if any. Depends on the results. But I expect to see a bunch, including child abuse, child endangerment, etc. She also had a 5-year-old boy in the room with all of the drugs (believed to be heroin), needles, etc.
