'One-punch victims' are mounting in Qld

Timothy Lang has tragically joined a growing list of six people to have lost their lives this year in alleged one-punch attacks in Queensland.

The 48-year-old Brisbane father's alleged attacker, Wayne Andrew Hearn, faced court on Wednesday, charged with one count of unlawful striking causing death.

The Newman government introduced the charge in 2014 following a spate of fatal one-punch attacks.

Those found guilty face maximum life jail terms and are required to serve 80 per cent of their prison sentence.

No one has yet to be sentenced on unlawful striking causing death, however Renata Armstrong, 22, has pleaded guilty to the new charge following the early morning death of teenager Cole Miller in Fortitude Valley in January.
