One dead, one injured in street shootings TWO shootings on Sydney streets just one kilometre apart that left one man dead and another injured happened within 90 minutes of each other but are not linked, police say. A 31-year-old man visited a house in Boldrewood Rd at Blackett, in Sydney's west, about 1.15pm (AEDT) on Saturday. He had a conversation with someone at the house before he was shot in the head while standing in the street, police said. The man died at the scene. "The victim in that matter attended that address for a particular purpose and consequently he was fatally injured," Superintendent Wayne Cox told AAP. Witnesses told reporters that they heard shots before hearing a vehicle speed off. Supt Cox said police were searching for a vehicle but would not confirm if the attack was a drive-by shooting. Police recovered a sawed-off shotgun in a nearby street and believe it is linked to the incident. Approximately 90 minutes earlier, a 21-year-old man had been shot in the leg outside his home in Hinkler Grove, Bidwill. The incidents happened just 1km from each other. In the case of the 21-year-old a vehicle had been hooning up and down the street before the victim came out of his home and confronted the driver. He was shot in the leg. He was taken to Mt Druitt Hospital for treatment. "It's a fairly significant action to be taken when you're dealing with a situation like that," Supt Cox said. He would not comment if the victims were known to police.
