Sydney shooting in Thorpe Place, Abbotsbury Distraught relatives at the scene of the shooting. A MAN was stalked for several hours before being gunned down in the front yard of a home in an "evil" and "brazen" execution-style attack. Police are seeking anyone who may have information about several men who may have been sitting in cars or walking in the area including one in a black hooded tracksuit who was seen walking around the property at Thorpe Place in Abbotsbury before the attack at about 10:05am today. "This is just a wicked attack," superintendent Peter Lennon said. This is a residential area, this is school holidays...for this to occur is just outrageous, despicable and wicked. Tyrone Slemnik was the victim of an overnight drive-by shooting. There may have been people who were sitting in cars or around that area (on) Thorpe place, Hackett road and Cowpasture road. We are making a major appeal to members of the public who may have been in the area and seen something. Heavy police attendance and dog squad follow reports of a shooting in Abbotsbury. The victim was treated by paramedics who conducted CPR at the scene in an attempt to save his life but he died at the scene. Police are yet to identify the man despite several individuals identifying as family members arriving at the scene and Supt Lennon said officers were waiting for the results of a fingerprint analysis. Residents in the area reported hearing "a couple of shots" before the noise of a car speeding away. Shortly after the shooting a woman, believed to be the victim's wife, earlier today arrived at the police line accompanied by a friend. "That's her husband," the friend called out. You've got to let her in its her husband. Distraught relatives speak to police.
