The last time Angela saw Evan was back at William's cabin in the woods. She was aware that Gael and his men had brought Evan to New York, but they didn't tell her how they did that, and she didn't ask either. The less she knew about Evan's whereabouts, the better.
She did find out that Gael kept him in The Bunk, but she hadn't seen Evan with her own eyes, and Gael wouldn't allow her to either. So technically, Angela had last seen Evan weeks ago in Esmea.
According to the article, General Leos hadn't heard from his son since the first week of February. Evan was on leave for 20 days only, and he hadn't reported back to work on the supposed date of his return a couple of weeks ago.
