In an article by CNN, a reporter has written a story about a mother who killed her teenaged children for being "mouthy".
For the lead, the reporter had to lead off with the notable part of the story, the suspect's motive. A mother killing her children because they were mouthing off gives a novelty aspect to this story, one that the lead should define.
This lead is also a hard-news lead, it leads with the action: two children being killed, and displays proper news writing.
