SAN JOSE — Police are seeking witnesses to a confrontation outside a downtown San Jose nightclub that resulted in the death of a 24-year-old Palo Alto man early Saturday.

San Jose police were alerted about 4:50 a.m. that a man suffering from head trauma was taken by friends to Stanford Hospital, where he died. Following reporting protocol, the hospital contacted Palo Alto police, which determined the man had been injured in San Jose.

Police spokesman Sgt. Enrique Garcia said a preliminary investigation also determined the man was involved in a fight at Myth Taverna & Lounge, a restaurant that also operates as a nightclub at Post and San Pedro streets. He was dropped off at the hospital a few hours later.

The case is currently being treated as a suspicious death, but SJPD homicide detectives are investigating because they handle all death cases in the city.

Additional details about the incident, and the victim’s identity, were not immediately released by authorities.

SJPD investigators ask that anyone with information about the fight or the victim’s whereabouts after he left the nightclub contact Detective Sgt. Raul Martinez or Detective Jorge Santiago at 408-277-5283 or leave a tip with Silicon Valley Crime Stoppers at 408-947-STOP (7867) or with svcrimestoppers.org.
