WINONA, Minn. – Two boys fishing at the East End marina told police that a stranger descended on them yelling and screaming. They reeled in their gear and walked to another fishing spot. The man came at them again, still threateningly, they said. The boys, age 16 and 15, got in their car to leave. But in backing out, they struck a post. There was no damage, but they decided to notify police anyway. They also relayed an account of the verbal assault. Officers located the man who the boys identified as their assailant — a 27-year-old known around town for inexplicable outbursts. This was about 2:25 p.m. A disorderly conduct charge was being considered.
