OAKLAND (CBS SF) — Police in Oakland were investigating a Monday morning homicide that marked the city’s 100th homicide after a deadly week, with Oakland’s police chief expressing frustration over his repeated public appeals to stop the violence.

The fatal shooting near the Coliseum BART Station on San Leandro Street happened at around 10:40 a.m., according to reports.

Chopper 5 was overhead as responding police officers were taping off the scene.

So far, authorities have released no word on the victim or a motive, but police said the fatal incident marks the 100th homicide of the year, compared to 70 this time last year.

An exasperated Police Chief LeRonne Armstrong addressed the recent spike in violence on his city’s streets Monday afternoon, saying ten people were killed in Oakland in the space of a week.

“We can be vocal about certain things. I just don’t understand why this community can’t be vocal about a hundred lives lost,” said a clearly frustrated Armstrong. “We can scream and yell about anything that the police department does wrong, but in this time, we cant speak up about what’s plaguing all of us. And that’s gun violence.”

The chief acknowledged that he was repeating himself at many of these news conferences addressing the rising tide of violent crime in Oakland.

“I just ask that everyone come together collectively to say that this has to stop. I say this every time we have a press conference,” explained Armstrong. “I am tired of appealing before you; we gotta do the work.”

Authorities also said there were 44 instances of gunfire in the past week. Officers recovered nearly two dozen firearms during that period. Additionally, officers investigated 17 robberies that happened in the past seven days.

The press conference came a week after Oakland experienced an extraordinary amount of violence in the space of 24 hours that started Monday afternoon with a double-homicide, an officer-involved shooting, a triple-shooting, and a stabbing, and ended with a fatal shooting early Tuesday morning.
