TOPEKA, Kan. (WIBW)-Jim Leavelle spoke at Washburn University Tuesday to share his story and several Kansas police officers were there to learn from his experiences as an important police officer in history.
On November 22 1963, President John F. Kennedy was assassinated while riding in a motorcade through downtown Dallas.
And 2 days later, Lee Harvey Oswald, the man arrested and accused of killing the President walked through a side-door of the Dallas Police Headquarters. He stepped into a crowded basement.
Leavelle was handcuffed to Oswald's right when Jack Ruby moved quickly toward Oswald and fatally shot him at point blank range.
"I armed myself with two 45's that day just in case, but it happened so fast I wasn't able to use them," said Leavelle.
It was a Sunday morning and Americans were watching the incident on live television.
"We were riveted towards our television for days," said Ron Brown.
Its been almost 50 years and now the 92-year-old Leavelle is at Washburn University to share his story.
" A major event like that can make a huge change," said Brown.
"It gives a perspective from law enforcement," said Herman Jones.
After the assassination, there were numerous conspiracy theories that Oswald did not act alone.
However, Leavelle says he spent many months studying the case and says Oswald was the lone gunman.
"I can prove it beyond any shadow of a doubt had we got to go to trial," said Leavelle.
Leavelle retired in 1975, after 26 years in the Dallas Police Department.
