I wasn't aware there was discussion about a "strange man"? Was there a different report than this one?
...."Sgt. Holeman tells us investigators recovered more audio from Libby’s phone, which was found with the girls at the crime scene.
“It does not appear to be anything more than some discussion between the girls. We have only released a portion of it. There are some others we think could help us but again protecting the integrity of the investigation is key so we cannot release everything because there are certain people that know the details and if we release it all then we get into false confessions,” said Sgt. Holeman..."

Adding this link. But it still doesn't refer to the man as " strange".
".....Police say the girls mostly talk about "stuff girls talk about" in the recording, but they also mention the man. The only audio that has been released to the public from the phone is that of a man's voice ordering German and her friend, Abby Williams, "down the hill."......
