WINONA, Minn. — Two men at the downtown warming center got into an argument over a girl and one drew a knife on the other. Or so police were told. The incident was reported to police about 9 p.m., inexplicably 11 hours later. Police questioned the men, neither of whom wanted to press charges. One man said, however, that the other man had slashed tires on his bicycle in the alley behind the basement warming center at 69 East Third Street.
