Teresa's Troubles

Riddle: Teresa found her friend Andy unconscious on the floor of his studio in the attic. The girl called the police; when the officer arrived, she told him her story. Teresa said, "I was walking past Andy's house when I saw, through the window, that the light was on. I also found that Andy was lying in his room; he didn't look too good, so I rushed inside and immediately called the police,". The officer didn't believe Teresa. Do you?
