SAN JOSE -- A 26-year-old man has been identified as the victim of a deadly downtown stabbing early Thursday across the street from Cesar Chavez Park, according to San Jose police.

Jason Rosario, whom police described as a local transient, was found gravely injured near Market Street and Paseo de San Antonio around 12:20 a.m. Thursday. Arriving officers saw Rosario was suffering from at least one stab wound, and he was rushed to the hospital, where he was pronounced dead.

No suspects or motives have been announced in the attack, which marked the city's fifth homicide of the year.

In what police believe was an unrelated instance, a man suffered life-threatening injuries early Friday after he was stabbed a few blocks south from where Thursday's attack occurred. The most recent victim was taken to the hospital with critical injuries. Similarly, no motives or suspects were immediately identified.
