Southern Division homicide detectives are continuing investigations into the murder of a Santa Flora man near his home on Sunday.
Dead is 47-year-old Trevor Hospedales.
According to reports, Hospedales was sitting on the roadside near the SS Erin Road around midday with his stepson, a Venezuelan national, when a man, armed with a gun, walked up to them.
On seeing the gunman, Hospedales and his stepson ran in different directions, but the gunman chased Hospedales and fired a dozen shots at him.
Hospedales was shot in the head and back and died at the scene.
The gunman escaped in a waiting car.
Police have requested closed-circuit camera footage from homes in the area to assist in the investigation.
