There is new information in the July altercation that left political consultant David Mercer hospitalized with a serious head injury. FOX 5 has learned no criminal charges will be filed and the case is now closed.
After weeks of investigating, police and prosecutors are now satisfied what happened to Mercer was not a crime.
Law enforcement sources say the man who hit Mercer claimed he did it in self defense.
Last July 12th at around 10 p.m., Mercer walked into the 7-Eleven on Maryland Avenue in Northeast D.C. where he apparently got into a dispute.
Law enforcement sources say Mercer apparently thought a man inside the store stole something from him and reached into the man's pocket to retrieve it.
As the men left the store, the dispute apparently escalated.
"What I can say at this time, this is not a random assault," said D.C. Police Commander George Kucik days after the incident. "We do not believe this involved a robbery, but there was a dispute between the complainant and another individual and it turned physical at some point."
When Mercer left the 7-Eleven, law enforcement sources say he was hit once in the face and fell backward, hitting his head.
The man who threw the punch claims he was defending himself.
At Mercer's Capitol Hill home on Friday, there was no answer. His next door neighbor, Darrin Howell, says he hasn't seen the consultant since the attack, but hears his health is improving.
He was not happy to hear the case is closed.
"I'm definitely disappointed," said Howell. "I've known David for over a decade. He's a brilliant guy, and to think he's been permanently impaired because of this incident, it just breaks my heart there can't be any more action that would help lead to more justice to take place."
Mercer's exact condition could not be learned.
Until he was injured in July, Mercer was a frequent guest on the cable networks sharing his expertise on the political races.
FOX 5 was unable to reach Mercer or any of his family members for reaction.
One other note: some media outlets reported in the days after the incident that Mercer's phone was stolen and showed video that appeared to bolster the story. Police say that never happened.
