A Shooting kills a Son and Leaves A Father Wounded

The article I am writing about is entitled "Shooting leaves son dead, father wounded in NE Philadelphia." The article I am writing about can be found on http://www.philly.com/philly/news/20120521_Shooting_leaves_son_dead__father_wounded_in_NE_Philadelphia.html. The police are investigating a shooting that left a son dead and the father wounded. A argument is said to be the reason of the killings. The son was 26 years old and the father was 50 years old.  The killing happened on 1200 block of Adam street. The shooting took place right in front of the son's house. The older man was shot once in his left arm. And the son was shot three times. Both the father and the son were taken to Temple University Hospital. The son Edwin Pagan died at 11:30 p.m. The father was an off duty corrections officer, and his wounds were more minor than the sons and he was treated and let out of the hospital. The investigators said the father was drunk when they came. Witnesses said they saw the father shooting in the air with a gun, but unfortunately the witnesses didn't see or know who shot the two men. The police really couldn't put all their focus and attention on the case because they are still in the middle of solving other homicides. I think this is a very sad and unfortunate thing that happened to these men. Even though I don't know what Edwin did to get shot and I don't know what the argument was about I still feel like it didn't have to reach this point. I think the story is very bland. It doesn't have any detail about what really happened. I mean I think the story is missing a lot of information. I hope when the detectives investigate the case they can find out more facts about what happened the day of the shooting and prior to that.
