As the family of slain Cambodian activist Kem Ley rebuild their lives in Australia, his youngest son, born just months after the assassination, acts as a human timepiece measuring the years since the five brothers lost their father.
Kem Ley, a popular analyst and critic who dabbled in grassroots politics, was shot at point-blank range at a gas station cafe in Phnom Penh in 2016.
An unemployed former soldier confessed to the killing and claimed the motive was an unpaid debt, in a trial critics say was a political cover-up.
