S16·E53 Lullaby: Part I

Smithy and Rickman attend a break in at a primary school and find a seven-year-old boy looking for food. Further investigation reveals that the boy has been living alone for three days and his parents are nowhere to be seen. Interviewing the family's friends and relatives, Deakin discovers that it is very unlike the parents to just disappear without trace, and CCTV footage shows a van watching the family's house on the night of the disappearance. Blood found in the family bedroom indicates the parents may have been harmed, but Deakin is furious when a racial attack on the restaurant where the boy's father works is found to have been investigated by Smithy over a week previously.
