MADISON, Wis. -

Madison police said a Good Samaritan was robbed Tuesday after he offered a man a cool place to stay during this week's heat wave.

Police said a 23-year-old man said he encountered a homeless man, Quincy Franklin, 26, on State Street about 1:30 a.m. Tuesday and saw that the stranger was in need of a cool place to sleep.

The downtown resident took Franklin to his air-conditioned apartment on North Frances Street and let him sleep on his couch.

The 23-year-old man told police Franklin showered in the morning and asked the victim for some clothes. After refusing the man's initial offering of clothes, police said Franklin decided to put on a Nike T-shirt and Nike sweatpants, but the victim didn't want to give up those particular garments.

There was an argument, and the victim said Franklin pulled out a multi-tool. The victim feared he might be stabbed, and backed off.

Police said Franklin left the apartment with the clothes and the victim followed him, notifying the building manager of the robbery.

According to police, that's when Franklin stripped down outside to only his red boxer shorts and sneakers and waited for police to arrive. He told officers that he did threaten the victim with a knife but since he took off the clothes, he did not believe he committed any crime.

But the officer, after investigating the totality of the incident, did not see it that way, according to a Madison Police Department incident report.

Police arrested Franklin on charges of strong-armed robbery and carrying a concealed weapon and on a parole violation.

The teary-eyed victim told police he was just trying to be nice, but he learned not to invite strangers into his home.
