The tense police action in which police positioned themselves outside a triplex for about nine hours began with the shooting of a man in the 2100 block of Del Paso Boulevard.
Police said gunshots in the area around 1:15 a.m. Not long after that they were told that a man was "down and out" in an alley behind a store, according to a department spokesman.
Officers found the man dead from trauma to his upper body. It was not immediately known what caused his death, a shooting or beating, but police later confirmed it was from a gunshot wound.
Police were told by witnesses that several people ran from the area. Officers traced them to the triplex nearby in the 600 block of El Camino Avenue.
Roads near that location were shut down as officers tried all morning to coax possible suspects from the residence beginning at 3 a.m. At least two people exited the residence early-on and were detained by officers.
SWAT officers were later able to get a man and woman to leave the triplex about 9:30 a.m.
Eventually, officers were able to search the triplex. However, no suspects were found in the search that ended about 11 a.m.
Police did not say if the four people who exited the building during the police operation were arrested. Police said they were told a man named "Heavy" was in the triplex, but he apparently was not found in the search.
