The rifle in question made at least one trip to Harford County immediately following the assassination to test if it indeed was the firearm used to take the life of the young president.

In the 1960s, H.P. White Laboratories, an independent ballistics testing facility in Street, had a contract with the Federal Bureau of Investigation for testing services.

Though the original owner of the lab, Henry Packard White, sold the laboratory many decades ago, Lester Rohane, chief engineer at H.P. White Laboratories for the past 30 years, said a single document was found connecting Lee Harvey Oswald's rifle to the lab.

"When people came asking about the rifle many years ago, we dug through boxes looking for the file," Rohane said. "The file was empty except for a single piece of paper from J. Edgar Hoover thanking Mr. White for his services."

According to reports from the 36th U.S. President's commission, known as the Warren Commission, the lab allowed three marksmen to test fire a Carcano rifle to determine if anyone could successfully fire the three shots Oswald is said to have fired in the 5.6-second time frame highlighted in the famous home-made movie Abraham Zapruder filmed that shows the president's assassination.

Reports confirm one of the three marksmen was able to successfully fire the three shots in the allotted time.

Donald Dunn, who purchased H.P White Laboratories from White, and sold it in the 1990s to an international company, said he was called on in the 1970s by CBS' famous journalist Walter Cronkite to recreate a test situation of the Kennedy assassination to confirm the shooting could happen.

"We tested for effectiveness and accuracy," Dunn said in a recent interview. "We built a tower that was in relation to the sun and a little road all in relation to the Texas School Book Depository [where Oswald fired the shot]."

Dunn said they gathered about 40 shooters ranging from expert Olympic shots, military men, police officers and newbies to test a Carcano rifle in the demonstration. He said about 30 shooters were able to hit the marks in 5.6 seconds.

Later, Dunn was asked to testify before the Select Committee on Assassination. Dunn said during the hearing there was a lot of discussion about a "pristine bullet," which wounded then Texas Gov. John Connally and Kennedy, yet had no markings aside from a small dent.

"All these experts said no bullet could have gone through that amount of material and remain pristine," Dunn said. "We tested in a set up using plastic materials set up like bone material to mimic the scenario and we proved it could be done."

But just as conspiracy theories about the assassination of President Kennedy continue, so does the president's legacy in Harford a half century after that fateful day in Dallas.
