The lead of a news story is one sentence that shares vital information to quickly grab the attention of the reader into the story. News elements included in a lead are the 5 Ws: the who, what where, when, why and/or how. With the Ws, the lead summarizes the most important information, without much detail unless it is critical to the story.
A reporter may choose a non-straightforward lead to deliberately tease your readers by withholding key information until your second paragraph. This is common in blind leads or leads in creative writing, not hard news.
