WASHINGTON, D.C. (WUSA) -- Nearly one year later, Paul Casey is still looking for answers, and justice.
It was September 23rd of last year, about two o'clock in the morning, when Casey's son, Pat, a former soldier who served in Afghanistan, was with some friends at the McDonald's at 19th and M streets downtown.
Police said Casey was annoying other customers and, after blocking the door to the restaurant, got into a fight with a group of young men. According to police, just outside the McDonald's, Casey was either punched or pushed, and hit his head on the pavement when he fell. Six days later, he passed away and, to date, nobody has been charged with his death.
Now, Casey's father says a surveillance video from inside the McDonald's completely undermines the police department's contention that Pat was bothering customers.
"We don't see Pat as being an instigator or being at fault here," said Paul Casey.
Paul Casey says the police investigation into his son's death was "sloppy" and he's determined to learn the full story of what happened outside that McDonald's.
"No person who had a loved one die in a situation like this would look at this investigation and be satisfied," insisted Casey.
In response, MPD issued the following statement: "All of the witnesses to the event, and the video in the case, were brought to the U.S. Attorney's Office for review. After reviewing all of the evidence in the case, the U.S. Attorney's office decided that there was not enough evidence to proceed with a prosecution. Our continued sympathy and condolences are with the Casey family as they struggle to come to grips with this tragic loss."
