Roy R. Botello will never forget the crowd's enthusiasm as he recorded a home movie of John F. Kennedy at a Houston hotel on the eve of the president's assassination in Dallas.

New color video footage showing President John F. Kennedy's arrival in Dallas the day he was assassinated is the best home movie ever made of the event, the curator of the Dallas JFK museum said.

As the nation marks the 45th anniversary Saturday of the Kennedy assassination, the 88-year-old detective Jim Leavelle remains one of the investigation's most famous figures.

The film shows a clear glimpse of President Kennedy and the first lady a few blocks from Dealey Plaza and roughly 90 seconds before the killing. Also visible is Secret Service agent Clint Hill riding on the back of the car.

Today's 43rd anniversary of the assassination of President Kennedy has been marked by visitors to the museum in Dallas where investigators say the fatal bullet was fired.
