I know that. That's why I verified with another source. Here's a third.

The 30-second shootout left three cowboys dead and Virgil Earp and Morgan Earp badly wounded. The shootout actually took place in a vacant lot near the intersection of Third Street and Fremont Street behind the OK Corral next to C.S. Fly's Boarding House and Photo Studio. The shooting started when Billy Clanton and Frank McLaury cocked their pistols. The Earps and Doc Holliday were arrested for murder by Sheriff Behan. At the trial following the gunfight, it was determined that the Earps acted within the law.

And a fourth:
Gunfight near the OK Corral
The place was Tombstone, Arizona territory. The time was Wednesday afternoon, October 26, 1881 and the setting was a vacant lot in the vicinity of the stables and sheds of the O. K. Corral. But the frightened horses landed the O. K. corral as the name forever to be remembered by the showdown.
