Here is the lead for the story of the pair going through the ice on Lake Minnetonka by the Star Tribune:
"A man in his 30s and an elderly woman whose vehicle plunged through the ice of a channel on the east side of Lake Minnetonka have died, authorities said Sunday."
The news elements that are in the lead are the who, what, where and when. We get the basic information that hooks us into the story, yet doesn't give everything away. The news writer details the age of the "who" and the "where". Because of all of the recent deaths and injuries on this lake due to people going through the ice, the writer probably deemed it important to detail the "where" and also the "who" to compare to past stories related to this.
Not all leads need to include the "when". This writer could have believed that the "when" was important because this lake has had a few incidents like this in the past month. To include the "when" emphasizes the point that these incidents are happening quite close to each other and people are not adhering to the danger of being on this lake, especially in a vehicle.
Since this is a local paper and a relatively small story, the lead is a straightforward hard-news type. More popular papers or bigger stories, sometimes a continuing story or investigation, the lead is more storytelling-like and is not worried so much about getting the generals but more on introducing the story.
