Final answer:
The victim likely discovered the burglary upon returning from vacation on July 8, 2008, after 11:00 am, as this is when the unauthorized entry and theft was noticed.
Step-by-step explanation:
The question pertains to when the victim discovered the burglary at their residence. Based on the information provided, Officer Harris was responding to a residential burglary that the victim said occurred while he was on vacation from July 2, 2008, at 4:00 pm to July 8, 2008, at 11:00 am. While the exact time the victim discovered the burglary is not stated, we can infer that it was discovered upon his return on July 8, 2008, sometime after 11:00 am, which is when he noticed the unauthorized entry and missing property.
The victim would have discovered the burglary to his residence when he returned from his vacation and found that his property was missing. Since he stated that the burglary occurred while he was on vacation between 7/2/08 at 4:00 pm and 7/8/08 at 11:00 am, he would have discovered the burglary after 7/8/08 at 11:00 am. However, the exact time of discovery is not provided in the given information.
