Many thanks to Yamilet Ayca for sharing the photo that she took with Keanu Reeves at the airport and to @keanulatino for tweeting the link. The photo is here.
Update: The photo is from April 8 when Keanu arrived. I have also been messaging with someone in Spanish and their info was that he was headed home. I am dependent on the translator and have asked for clarification on their message. I have also reached out to another source. I will update if I find anything else out.
Update X2: Initial report was that he left Chile after the trip to Vina del Mar but it was another person in the party that left. It is not clear if he is still at the hotel according to the source. I am assuming he is still in Chile for the time being. The second source has reported in and says he is still in Chile. I’m going to bed so any additional updates will have to wait until tomorrow.
Update X3: From the interview in La Tercera, it sounds like Keanu will stay in Chile for several more days.
Note: Sorry for the confusion. I do the best I can with the info I have and the language barrier is making it more difficult.
