This is why we lock our doors.
Madison police said an 18-year-old Chicago man walked into an unlocked West Gorham Street apartment in the middle of the night, took off his socks and pants and then used the toilet to such an extent it took two hours to clean.
The nastiness was reported to police a week ago during the night on Oct. 9-10, said police spokesman Joel DeSpain.
"The 19-year-old resident and his friends were aghast to see and smell what had transpired while they slept," DeSpain said.
The resident first came upon the stranger when the stranger walked into his room and turned the light on.
"He then heard the man go to the bathroom and leave the apartment a few minutes later," DeSpain said.
In the morning on Oct. 10, the apartment dwellers realized something was amiss.
The stranger's cell phone and identification were found in the bathroom, along with his socks, pants, and night deposit.
A roommate left the door unlocked.
"They won't be doing that again," DeSpain said.
An investigating officer discovered an e-mail address for the night visitor.
"He (the officer) let him know how to get his property back and advised him that it would be very adult of him to apologize to the people in the apartment," DeSpain said.
The apartment residents didn't file a trespassing complaint.
