Vallejo Mayor /*Osby Davis*/, the city's police chief and the /*Solano County*/ sheriff say deputies will help assist city patrols.
Vallejo is also asking the CHP to step in during the summer.
This month, there have been two murders, the beating of a city employee, the shooting of an ice cream truck driver and a triple stabbing.
The city has cut more than a quarter of its police force since 2007 as it struggles to emerge from bankruptcy.
