OAKLAND -- One man was killed and three of his relatives were wounded in a shooting after a family gathering early Saturday morning, police said.
Augusto Matias, 34, was hanging out with his brother and their two cousins in front of a residence in the 1600 block of 28th Avenue when a man approached them on the street and opened fire about 3:50 a.m., authorities said.
Matias was pronounced dead at the scene, and the three other victims were sent to a hospital, police said.
Two victims are in stable condition, while another was critically wounded and underwent emergency surgery, officer Kevin McDonald said.
The men -- each a laborer who immigrated from Guatemala -- were continuing a celebration that began with a relative's graduation party Friday evening, officer Eric Milina said.
Matias' brother is 37, while one cousin is 28 and another is in his 30s, authorities said.
Police said they do not yet have a motive or a suspect description. No arrests have been made.
