OAKLAND, Calif. — The Oakland Police Department's homicide unit has received a small boost this year, one that police commanders hope can make a big difference in solving the most serious of crimes in a city known for a high murder rate.
Oakland homicide investigators regularly work twice as many cases if not more as their counterparts in other cities, and the department, to date, has solved less than one-third of its homicide cases from 2008.
