Logan Mwangi's mum drastically transformed her appearance weeks after murdering her son in the hopes of avoiding recognition.
Angharad Williamson, 31, was sentenced to life imprisonment for killing the five-year-old alongside partner John Cole, 40, and their stepson Craig Mulligan, 14, whose identity was revealed this week.
Logan suffered catastrophic injuries similar to those seen in high-speed car crash victims before his body was dumped like "fly-tipped rubbish" into the River Ogmore near his Bridgend home.
