I hope it gets clarified:
1 - why he apparently didn't tell the 911 person directly that there was an intruder and that he was in danger (she had to read between the lines?)
2 - why the intruder allowed him to use the restroom (and then call 911)
3 - why the intruder was in his underwear
On the surface it would appear that the person may have been well know to PP?
Very weird.
