- It has been almost a year since Democratic National Committee staffer Seth Rich was murdered in the nation's capital. There have been no solid answers about why he was killed until now.

Rich was shot and killed last July in Northwest D.C and police have suggested the killing in the District's Bloomingdale neighborhood was a botched robbery. However, online conspiracy theories have tied the murder to Rich's work at the DNC.

Just two months shy of the one-year anniversary of Rich's death, FOX 5 has learned there is new information that could prove these theorists right.

Rod Wheeler, a private investigator hired by the Rich family, suggests there is tangible evidence on Rich's laptop that confirms he was communicating with WikiLeaks prior to his death.

Now, questions have been raised on why D.C. police, the lead agency on this murder investigation for the past ten months, have insisted this was a robbery gone bad when there appears to be no evidence to suggest that.

Wheeler, a former D.C. police homicide detective, is running a parallel investigation into Rich’s murder. He said he believes there is a cover-up and the police department has been told to back down from the investigation.

"The police department nor the FBI have been forthcoming,” said Wheeler. “They haven't been cooperating at all. I believe that the answer to solving his death lies on that computer, which I believe is either at the police department or either at the FBI. I have been told both.”

When we asked Wheeler if his sources have told him there is information that links Rich to Wikileaks, he said, “Absolutely. Yeah. That's confirmed."

Wheeler also told us, "I have a source inside the police department that has looked at me straight in the eye and said, ‘Rod, we were told to stand down on this case and I can’t share any information with you.’ Now, that is highly unusual for a murder investigation, especially from a police department. Again, I don’t think it comes from the chief’s office, but I do believe there is a correlation between the mayor's office and the DNC and that is the information that will come out [Tuesday].

A full report with the new details will air Tuesday morning on FOX News.
