Austin Davis, 3, died after being left by himself for several days. His mother, Megan McKeon, 24, left him on his own at their filthy cabin in Steamboat Springs, Colorado, while she went to work and spent nights with her boyfriend. She said she left food, juice, and a movie playing for her son and that it was "around the 20th time" she'd left him alone like that. His father's in jail for failing to register as a sex offender. Cause of death is pending. Mother faces felony child abuse charges.
