What is the history of the building?

Rosa's is famously built upon the grounds of the "massacre at new mesa" that happened in 1865. It was there that the settler party of Tom Mesa was discussing the terms of the cattle drive with Bob University, an experienced cowboy. University felt that Mesa was cheating him on the price of the drive. University ultimately insulted Mesa's mother which Mesa was notoriously sensitive to "your momma" jokes and Mesa drew his pistol and the slaughter commenced. Both men died but neither from any bullets. University, attempting to duck from the gunfire, fell face first in a large cow pie and suffocated. Mesa was thought to have died from a stray Indian arrow but in 1972 a historic autopsy found that the actual cause of death was from a toe nail that was ripped off during the gunfight causing Mesa to bleed to death in a matter of minutes.

I don't know the history but the review above me is pretty awesome!
