Investigator Robbins is called to the scene of a robbery. The officer on the scene thinks that the suspect entered the home from
the garage. As Investigator Robbins checks over the house, he does not find any evidence of forced entry. He cannot find any physical evidence near the garage door at all. There is a window open above the kitchen sink and footprints in the mud under the window outside. Based on his examination, what conclusion might Investigator Robbins make? 1. The officer was correct; the garage was the point of entry.
2. There is no evidence to indicate that anyone entered the home.
3. The officer's conclusion was mistaken, and a suspect may have entered through the window.
4. The garage was the point of entry, but the window was the escape route.
