MEQUON, Wis. -

Authorities say it was a bee or wasp sting that killed a man in Ozaukee County.

Relatives said 46-year-old Vladimir Novak was sitting outside at his home in Mequon Monday when he was stung and went into shock. A neighbor, who is a doctor, rushed over and tried unsuccessfully to save Novak. He was pronounced dead at Columbia-St. Mary's Ozaukee.

County Coroner John Holicek told the Journal Sentinel Novak's death is the result of anaphylactic shock. Holicek said it's only the second fatal insect bite in the county in his 23 years in office. In the other case, a child died after being stung by a number of bees.
