OAKLAND -- Five fatal shootings. At least another 15 people wounded by gunfire.
The bloody tally of death and injury in the past week prompted Chief of Police Howard Jordan on Tuesday to say he is using extra patrols, partnerships with other law enforcement agencies and technology to combat the violence.
But as he and other police commanders have said before, police cannot fight crime alone, and he implored the community, including clergy, business people and residents, to join the battle.
"Our department can't do it alone," said Jordan, as community members joined him at a news conference Tuesday.
"I ask you to stand with me and with our community leaders here today to make our city safer," he said, appealing to the public.
Oakland police also on Tuesday released the names and pictures of four people who are in some way linked to the recent shootings. Shameko Cobb and Nicholas Williams are wanted on warrants, Robert Drawn is a homicide suspect, and Chau Van is wanted in a shooting, said Officer Johnna Watson, police spokeswoman.
"These are the most dangerous and the most wanted people in our city," Watson said. "These are the people we most want off our streets."
Police declined to release additional information about the four because of ongoing investigations. Of the violence that erupted last week, Jordan said, "We can't let that continue. We have to address the crime before it gets out of hand."
He said the spike in violence was due to ongoing disputes between gangs in both West and East Oakland. Police said at least two of the killings and half of the other shootings can be linked to gang warfare.
Jordan said he has increased patrols in known violent areas and plans to have officers work more with parole agents and probation officers to deal with known offenders. He said arrests have been made in four of the killings, and there are good leads on several cases. Officers have also seized at least 20 guns in recent weeks, including some that were displayed for the media.
The federal Bureau of Alcohol, Tobacco, Firearms and Explosives is working with Oakland to reduce the violence, he said. ATF is offering $5,000 rewards for information leading to the arrest and prosecution of anyone involved in firearm violence. A tip line, 510-517-8793, has been set up for callers.
"There is no shortage of guns on the street. That is why we need the public's help," Jordan said.
U.S. marshals are also assisting the city in its crime fighting.
The chief said the ShotSpotter technology has enabled officers to get to shooting scenes faster. In Monday's killing, it allowed officers to find the suspect more quickly. He said in that case police did not get a call from residents about gunfire until 20 minutes later, and he said calls should be made much sooner.
The homicide clearance rate is not as high as he would like. He said 15 teams of investigators would be "ideal" for solving more cases, but he only has five teams, who he said "are doing the best they can."
He said that although Occupy Oakland protests are stretching the department's resources even thinner, that has not really been the cause of increased violence. Gang members are not watching the protests, he said, but instead will shoot at a rival whenever the opportunity arises.
