MINNEAPOLIS — A 19-year-old man is charged with a misdemeanor after authorities say he jumped off a bridge in a Twin Cities suburb in the name of charity.

The Hennepin County sheriff’s office said Monday that Joseph Mark Sanislo of Coon Rapids is charged with one count of disorderly conduct.

Sanislo jumped off the Highway 610 bridge in Brooklyn Park last week while wearing a life jacket. The sheriff’s office says Sanislo told investigators he was taking part in the “cold water challenge,” in which people jump into lakes, rivers and ponds.
