The news lead works in this story because it gets right to the point of what the whole story is about. It is obvious that the reporter had to collect as many facts as possible to assemble the lead with maxium information without telling the whole story. It would be catergorized as a basic news lead and very straighforward. The lead in this story keeps the reader interested in what is next to come in the story, using words like conflict, arrested and murdered.
This particular lead contains all five W's. The who, what, where, when and why. Each of the W's contains enough information to let the reader know that specifics of the case are to come. However, everything in the lead are basically general. There aren't formal names except the mention of Yale and that the arrest happened on Thursday.
