Police in East Palo Alto were pleading for witnesses to come forward Tuesday in the city's first homicide of the year, which occurred the afternoon before.

East Palo Alto Police Sgt. Jeff Liu said witness accounts were still needed to help solve the case, which resulted in the death of 24-year-old Jonathan Alcazar, a city resident.

Alcazar was found by police suffering from multiple gunshot wounds and was pronounced dead at the scene just before 2 p.m.

Liu said police received a ShotSpotter activation alerting them to the midday shooting in the 2600 block of Illinois Ave. He said there were people milling about the neighborhood, so there was a likelihood that somebody could provide information to help solve the crime.

A second victim, who arrived at an area hospital with gunshot wounds, remains in critical condition, according to Liu. The name of that victim was not released by Tuesday.

Police had no suspect or motive as of Tuesday afternoon. Anyone with information was asked to contact East Palo Alto police at (650) 321-1112.
