I have no confirmation regarding LE. Sorry, I did not mean to imply that.
What I do have, though, is insight into the game. The rules of the game make it best to play when nobody else is around. Plenty of people have put it down and then later picked it back up again due to changes in the game. And plenty of people keep it to themselves because it is embarrassing. Why would I tell somebody I'm playing Pokemon Go if they think it is a "waste of time"?
If I leave my house to go hit the local pokestop, I just say I'm going for a walk. And I do think Pokemon Go is a waste of time. I play it anyway. Whatever. It's my time to waste.
At the time Toni died, there were 5 million daily users in the US. That's 1.6% of the entire US population. 60% of players are 18-34 year old millenials.

63% of players are female.
Five. Million. Players. Mostly female. And people think I'm crazy to suggest she was playing that morning.
Frankly, those people know nothing about the game and why people play it.
