AM Sacramento: Here’s what you need to know for Wednesday

Good morning. Here’s what you need to know today:

The heat is on: A ridge of high pressure will produce midsummer-like daytime high temperatures in the Sacramento area through Friday. Some areas could hit the 100-degree mark. National Weather Service forecasters say the Delta breeze and possible relief from the high heat might not come until Monday.

Frentzen the winner: Shiva Frentzen, a Cameron Park computer services consultant, cruised to victory Tuesday night in a special election to replace ousted El Dorado County supervisor Ray Nutting.

Better count needed: A city audit has found that the Sacramento Fire Department could do more to keep an accurate count of the potent narcotics it uses to administer medical care. The department has generally strong controls over its inventory of morphine and Versed, but “it could be better,” City Auditor Jorge Oseguera said on Tuesday. Oseguera said getting access to the drugs is a “very, very convoluted process” that includes signatures from multiple individuals. However, the department has not been conducting enough regular counts of its inventory of the drugs at its EMS central facility and had relied upon hand-written databases, leading to some inaccurate tallies.

Dire warnings: Daniel Marsh told an emergency nurse in the months before the April 2013 stabbing deaths of an elderly Davis couple that he had tried to end his life on three separate occasions. The Davis teen’s growing anger and ever-increasing thoughts of suicide, homicide and torture alarmed a school counselor enough to alert officials of a possible threat to fellow students and call police.

County hires: Sacramento County supervisors decided Tuesday to use $33 million in unexpected revenue to hire animal control officers and prosecutors and pay off debt, among other things. Supervisors made the decisions in approving the county’s $3.7 billion budget for the fiscal year that started July 1.
