It is not a false claim. Both Helen Markham and William Scoggins witnessed the killing and they both positively identified Oswald as the killer.
Yep, and both agreed that the jacketed Oswald while fiddling with his weapon described him as moving towards Patton, a fact verified by the Davis sisters and then just down Patton the jacketed Oswald who was still brandishing his gun was identified by Callaway and Guinyard, all these eyewitnesses are equally important because they all corroborate the exact same narrative.
