A man was airlifted to Denver for medical treatment on Oct. 29, after a fight at a Casper bar.
A bartender told police Alvaro Proa, born in 1995, pulled a knife on a bouncer at The Gaslight Social. The bartender initially thought that Proa had stabbed the bouncer, Lucas Sanchez. Court documents indicate that Proa had dropped the knife instead.
The bartender told police that Sanchez "choked the male out or submitted him somehow." Proa was described as lying on the ground, motionless.
Proa was taken to Wyoming Medical Center before being airlifted to Denver for further medical treatment, according to the documents.
Proa told police while at the hospital that he had a knife but did not remember brandishing it during the fight, according to the documents.
The documents indicate that a manager at the bar provided surveillance video for police to review.
Casper Police Sgt. Mike Ogden said no arrests had been made in relation to the incident. Ogden declined to comment on the medical status of Proa or Sanchez, citing the confidentiality of medical records.
Gaslight Social Co-Owner Matt Galloway declined to comment Tuesday when reached by phone.
A Spanish-language online fundraiser asked for help with Proa's medical expenses and listed his condition as critical.
