Jail employees will now be screened for drugs

San Diego County Sheriff Kelly Martinez announced that all personnel assigned to county detention facilities, including contractors, will be screened for narcotics and contraband. For the past two years, the Sheriff’s Department has rejected recommendations from the Citizens Law Enforcement Review Board to screen employees for drugs. Plus, the extreme heat gripping most of the county is coming to an end. But California’s grid operator is asking residents to prepare for Flex Alerts if hot weather continues. And UC San Diego researchers published a new study on comb jellies — invertebrates living miles under the ocean.
