Police were investigating a shooting that killed one man and hospitalized another in San Francisco's Crocker Amazon neighborhood Monday morning, a police officer said.

Officers responded to a report of shots fired in the 1100 block of Naples St at about 12:05 a.m., Officer Gordon Shyy said.

When officers arrived at the scene, they found two men suffering from gunshot wounds, Shyy said. The two men, who were cousins, were reportedly walking home from a nearby bar at the time of the shooting.

One of the victims, 43-year-old Daniel Colon, was pronounced dead at the scene.

The other, 34-year-old Andrew Colon, was transported to San Francisco General Hospital to be treated for multiple wounds to the upper body, Shyy said. His injuries were not considered life-threatening, he said.

Colon's relatives told KTVU later Monday morning that Andrew was shot through the lung and remained in ICU.

Police were searching for one suspect, a man described as white or Hispanic, who was last seen wearing dark clothing, Shyy said. The suspect fled the area on foot.

Family members, including Daniel Colon's mother Tina, came to the shooting scene and spoke with KTVU.

Tina Colon said that Daniel was the father of a 11-year-old son.

"I don't know who would want to hurt [Daniel] or my nephew," said Tina.

Anyone with information about the shooting was asked to call the San Francisco police at (415) 575-4444.

The homicide marked the city's third of the year.
