Police have filed a search warrant for the medical records of Salvador Serrano, revealing more details of what happened when he died on Oct. 26.

According to the warrant's affidavit of probable cause, State College Police Department obtained his medical records because they could possibly assist in determining the cause and manner of his death.

State College police filed the warrant with District Justice Carmine Prestia last week.

The affidavit said a bouncer of the All American Rathskeller, 108 S. Pugh St., had restrained Serrano facedown by using his body weight to hold him to the ground.

Police, who had been called to a fight at 1:47 a.m. on the 100 block of East Calder Way, tried to handcuff Serrano, but he was limp. Police attempted to resuscitate Serrano, and he was transported to Centre Community Hospital, where he was pronounced dead one hour later.

Police are attempting to answer several questions during their investigation, including why a bouncer continued to restrain Serrano while he was unconscious.

In a separate but similar June case, the York County Coroner's Office said David A. Potter Jr. died at a York bar due to sudden death during restraint, when bouncers held him facedown with at least one bouncer on top of him.

York County Coroner Barry Bloss said Potter did not die of suffocation, but his heart went into arrhythmia because he was unable to take in enough oxygen after physically exerting himself.

Police said Serrano and Brooke Morgan, his fiancée, were walking down Calder Way with another couple, Tim Padalino and Alison Bresnahan, when Padalino stopped in the gravel parking lot behind the Rathskeller to urinate. Rathskeller staff stopped Padalino, and a fight broke out between the two couples and four bouncers.

Bouncers restrained Serrano and his acquaintances, and police arrived on the scene in response to a call from a Rathskeller patron's cellular phone.

While an autopsy has been conducted, Centre County Coroner Scott Sayers is waiting for the results of toxicology and tissue analyses before establishing Serrano's cause of death. Sayers said last week that Serrano's lungs were not inflated as normal lungs at the time of his death.

This does not determine whether suffocation caused Serrano's death, although that possibility has not been ruled out, Sayers said.

Sayers said the amount of air found in Serrano's lungs was not unusual given the circumstances. The exhausting nature of the incident would leave any person with a lack of oxygen -- although not necessarily life-threatening, Sayers said.

Police officials were unavailable to comment about the warrant yesterday.
