Considering how inaccurate news reports tend to be when it's about something you are personally aware of, I'm guessing this article was pretty much written by the defense lawyer in an attempt to paint the prosecutor in a bad light. You have no idea how many important details could have been left out.
Like what? The facts of the case are pretty well laid out in the article. What are you suggesting they covered up that could really change our perspective of the case?
Even if the two teenagers were sleeping together that wouldn't change most people's perspective of this case, it certainly wouldn't change mine.
All I know is people who write these kinds of news reports with obvious motives behind them are strongly incentivized to misrepresent the facts or leave some out entirely. Maybe the boy is being charged with other crimes as well - bad ones, and this charge is expected to get dropped. The story just seems ridiculous as written, and that's usually a sign that there is much more to it than what they wrote.
What could possibly explain injecting a teen at a hospital to induce an erection? It's just plain disgusting even if there is a legal explanation (highly unlikely).
