Baker has not yet been arraigned yet because of his injuries, but he will be held on a $1 million bail in connection with the homicide and attempted homicide charges, Glass said.
According to the police news release, another man, identified by police as Brian McTeigue, 26, of Mission Viejo, was also stabbed.
An altercation between the three men broke out near the valet parking area after a New Year's Eve party had just ended at the hotel on Bristol Street in Costa Mesa, police said in the news release.
Both Sickles and McTeigue were transported to Western Medical Center in Santa Ana, where Sickles was pronounced dead and McTeigue is currently being treated for his injuries, Glass said. The police had been on scene and had been dealing with other disturbances at the time of the fatality, according to the news release.
Glass would not elaborate on the status of Baker's injuries, other than to say that he did not believe they were life-threatening.
An investigation is ongoing, and police are asking witnesses with information to contact either Detective Kevin Condon at (714) 754-5361 or Sgt. Ed Everett at (714) 754-5395.
